Introduction Calculating inventory levels in SQL can be tricky, especially when you need to derive values based on previous rows. In your case, we want to compute a new column, Avail_to_fill, which will be the difference between the Onhand quantity and the Qty ordered for each item. This calculation should depend on the preceding row's result. Understanding the Problem The table you provided has several columns: ORDER#, Date, Item, Qty, Onhand, and Avl Fill. The requirement here is to create a new column that shows the available inventory (Onhand minus Qty) line by line and restarts the calculation whenever a new Item is encountered. This behavior can be achieved using Oracle SQL's analytic functions and a common table expression (CTE) for structured queries. This technique incorporates th…  ( 4 min )

If you're adjusting your schema or moving platforms, you're doing database migration. Whether small or large, migrations help keep your app in sync with changing requirements.

In today's digital landscape, software developers face a significant challenge: convincing users that their applications are safe to download and use. As cybersecurity threats continue to evolve, users have become increasingly cautious about what they install on their devices. This is where code signing emerges as a crucial practice for developers looking to build trust and increase download rates. Code signing is a security practice that involves applying a digital signature to software or executable files. This signature is an electronic proof that the code comes from a specific publisher and hasn't been tampered with since it was signed.

What Is a Shadow API? A shadow API is an application programming interface that is created or used without explicit approval from the organization’s IT or security teams. Shadow APIs can emerge from various sources, including developers experimenting with new features, legacy systems that are no longer officially supported but still in use, or services integrated outside of formal IT channels. This is part of a series of articles about API security Unlike official APIs, shadow APIs lack oversight and governance, making them invisible to the security measures typically applied to known and documented APIs. They operate under the radar of standard security and monitoring practices. Because these APIs were not introduced through sanctioned processes, they are excluded from inventory or documentation efforts. As a result, shadow APIs present significant risks. They are not subjected to regular security assessments, patches, and compliance checks that would normally be part of an API’s lifecycle management in a secure software development environment.

Recently, I was brought on board of yet another project to help build an enterprise-grade IT solution based on Microsoft Power Platform and Azure. Like any well-architected system, the solution required robust observability — the ability to track operational behavior, diagnose issues, and maintain visibility across all components. Naturally, Azure Monitor was the go-to choice. One of the core components of the solution was a custom plugin for Power Platform. To capture application-level telemetry from the plugin, the obvious approach was to use a telemetry client that integrates with Azure Application Insights, a feature of Azure Monitor. By default, Application Insights allows unauthenticated data ingestion — which makes it a potential target for abuse. To address this, the instance was c…  ( 6 min )

First, let's see why we use this approach: Private keys and certificates may contain binary characters incompatible with certain systems (e.g., environment variables, .env files, YAML, JSON, XML). Base64 encoding turns them into secure ASCII strings compatible with virtually any transmission medium. Storage in environment variables/files Systems like Docker, Kubernetes, CI/CD (GitHub Actions, GitLab CI), and configuration tools (e.g., dotenv) handle text values ​​better. Base64 allows you to store keys/certificates directly as environment variables. PRIVATE_KEY_BASE64=LS0tLS1CRUdJTiBSU0EgUFJJVkFURSBL... REST, …  ( 5 min )

When transitioning from SQL Server 2019 to SQL Server 2022, many developers have noticed performance degradation in their SQL queries. One common scenario involves the usage of functions like DATEDIFF within complex queries.

It enables easy support for light/dark modes and beyond (daylight, retro, etc.) with minimal complexity. tailwind.config.js Isn't Enough for Theming Traditionally, developers define colors like primary, accent, or background directly in tailwind.config.js: module.exports = { theme: { colors: { primary: '#571089', accent: '#ea698b', …  ( 5 min )

In Rust, when using GTK's DropDown widget, you may want to execute a closure to retrieve the selected index upon the selection change. A common issue developers face is accessing the selected choice directly from the ParamSpec. Let's dive into how to do this effectively. Understanding the DropDown and Connect Closure When you create a DropDown in GTK, you define the choices it contains. In your example, you have created a DropDown with two options: let choix = ["Choice 1","Choice 2"]; let drop_down2 = gtk::DropDown::from_strings(&choix); Here, choix is an array containing the two options. The DropDown will display these choices in the user interface. To respond to user interaction, you set up a closure that will be executed whenever the selected choice changes. The…  ( 4 min )

In the vast universe of software development, Visual Studio Code has emerged as a key tool—an unexpected bridge connecting worlds that once seemed incompatible. It has become a lifeline for developers coming from the GNU/Linux ecosystem, desperately seeking a way to write desktop applications, something they thought was lost in their environment. Its versatility allows for development in C#, C++, and FPC Pascal, avoiding alternatives like Lazarus, and offering a more modern and robust option. Personally, I’ve found myself using it as an alternative to Visual Studio 2022, since developing a .NET 6, 7, or 8 application on Linux is financially more viable for my business than doing so on Windows. But here’s the question: Why does Visual Studio Code feel like an orphaned and underappreciated sibling compared to Visual Studio 2022? Both serve incredible purposes. Visual Studio 2022 is the enterprise-grade powerhouse, while VS Code is the agile alternative—the gateway for many developers coming from GNU/Linux, looking to explore Windows and its tools, or simply wanting to use .NET Core on Linux. That in itself is a massive achievement, a step forward in software evolution. Because in the end, bluntly speaking, Linux is great... but if it doesn’t pay the bills, what can I do? As developers, we need to produce high-quality software using high-quality tools. That’s why Visual Studio Code becomes the logical and efficient choice—a path that allows us to keep programming in diverse environments while maintaining productivity and financial sustainability. Ultimately, VS Code isn’t just a code editor… it’s the bridge that unites worlds that once seemed irreconcilable.  ( 3 min )

之前写的后台的控制程序，我采用的都是用VC或者是C#写完之后然后采用AlwaysUp或者是nssm把自己写的后台程序再给做成一个Windows的服务程序。但后来想了想为什么不自己直接写一个Windows的服务程序呢。所以就开始了写服务程序的历程。 首先大致的说一下C#语言写一个Windwos服务程序的方法。说实话C#想写一个Windows服务程序相对的要简单的多。因为C#已经都给准备好了。就在创建项目的选择Windows服务项目就可以了。然后再添加一个服务安装的组件，改一下相关的配置，如：服务名、启动类型、启动权限或者叫启动时的用户。这些信息就可以了。在写代码的时候只要在开始的里面写上服务启动时需要做的工作，在结束里面写上服务停止时需要收尾的工作就大功告成了。 下面主要是说一下采用VC写Windows服务程序。这个我个人觉得相对来说有几个坑需要避。 第一个坑就是如果你从网上查的话都会说用VC写Windows服务程序的入口主函数是ServiceMain()这个函数。而实际并不是，实际上的程序入口还是从main()这个函数开始的。只不过在这个函数中我们不能做太多的事情，必须要尽快的调用StartServiceCtrlDispatcher()这函数来启动ServiceMain()函数。而且ServiceMain()这个函数的名字也并不一定就是这个，可以自定义。只不过你在网上查的人都会采用这个函数名而已。并非VC语言的规定或者约束。这个函数也只不过是在调用StartServiceCtrlDispatcher()函数的时候的一个参数而已叫什么名字并不重要。 第二坑就是服务状态的变换问题，只有你有ServiceMain()函数中调用了SetServiceStatus()函数来告诉Windows操作系统你的服务程序是开始启动了还时正在运行之中还是正在停止之中才可以。在这方面我从网上查了好长时间没有一个写的清楚的。我开始的时候以为这个函数没什么大用于是把相关的代码给删掉了，结果就会发生服务程序的状态无法改变。比如你在启动服务的时候没有及时的状态改成正在运行的话那么Windows的服务控制台就会一直启动这个服务直到启动超时而报错最后服务的状态就会卡在启动状态无法将服务停止或者删除。如果你能将服务状态进入到正在运行状态，但在发出停止服务的时候如果不能将服务的状修改成停止的话那么Windows也会一直停止这个服务直到停止超时而报错。而且这个服务的状态也会卡在停止的状态无法改变。 第三个坑就是在ServiceMain()函数中在用SetServiceStatus()函数把服务的状态修改成“正在运行”的状态之后必须要调用WaitForSingleObject()函数把这个服务的主线程给卡住然就是是一直等待发出服务停止的信号。所以在真正的主线程中你是无法再做其它的任何的工作的。故如果要想写好一个完整的Windwos服务程序就必须在ServiceMain()函数调用WaitForSingleObject()函数之前将你想做的事情都给加载完毕之后再调用WaitForSingleObject()函数将主线程卡住一直等待停止服务的指令。当停止服务的指令来临的时候再调用SetServiceStatus()函数把服务的状态修改成已经停止。 第四个这个不算是坑了这个算是一个常识。就是服务程序的调试问题。如果想调试Windows服务程序那么就只能采用“附加到进程”的方式。即先从Windows的服务管理器中启动服务，然后从Visual Studio的“调试”菜单中选择“附加到进程”的选项然后再选择自己程序的那个进程就可以了。 总结一下，那就是不论是VC写Windows服务程序还是C#写Windwos服务程序，都会有一个开始服务的初始化函数。而初始化函数中不能有死循环，但一般的服务程序又必须要用死循环，所以一个完整的Windwos服务程序一定是一个多线程的，在初始化的时候就启动其它的想要加载的死循环的线程。还会有一个程序的销毁函数，同样在销毁函数中也不能有无法完成的循环。最后就是Windwos服务程序的调试必须采用附加到进程的方式来进行。  ( 2 min )

In Java, an array is a data structure that stores a fixed-size, sequential collection of elements of the same data type. It is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created and remains fixed throughout its lifetime. Arrays are used to organize data efficiently and can be defined and initialized in various ways. Array - Group of similar datatypes Why do you use an array? Arrays are handy when you want to work with multiple values of the same data type. Instead of declaring individual variables for each value, you can group them together in an array, making your code more concise and easier to manage.

When working with Bash scripts, managing file paths and filenames can sometimes lead to unexpected sorting behavior. If you're trying to sort an array of complete filenames and want them sorted by just the filename while retaining the full paths, you're not alone in this challenge. In this article, we'll explore a solution that allows you to achieve exactly that. Why the Issue Occurs The confusion often arises from how the sort command works in conjunction with the full paths of files. When you try to sort by default, it considers the whole string, which includes the path. This results in sorting that does not reflect the ordering of the filenames, as seen in your request where sort outputs filenames based on their directory path rather than the filename itself.

Bitcoin has reclaimed $98,000 for the first time in almost three months after the US Federal Reserve said it would keep interest rates the same for another month. The Fed’s decision to keep interest rates unchanged comes despite mounting pressure from US President Donald Trump, who just weeks ago threatened to fire Fed chair Jerome Powell for being “too late” in cutting rates. Fed cites higher unemployment, inflation risk Powell said on May 7 that the Federal Reserve rate-setting committee held rates in the 4.25% to 4.50% range due to the rising risks of higher unemployment and higher inflation. He added inflation has “come down a great deal but has been running above our 2% longer objective.” Powell said surveys in households and businesses showed a “sharp decline in sentiment” mainly due…

Static method is a method bound to class and not the object of class. To define static method we will use @staticmethod decorator. Explanation: If you want somebody not to access specific function through object you can do it by applying the @staticmethod. And do not pass 'self' because it will create connection with other attribute. But if you seen closely general_description is accessible through object and class also. So the question arises does this statement defy us. Well answer is, Yes, it does. Here is analogy: You will kept your screwdriver, hammer or nickel in toolbox, so that somebody want to access it he/she will look for toolbox. If you travel through airplane doesn't which model of airplane you travel the manual of that plane will remain same like how to tie seatbelt. Same as goes for static method you just access static method function through class not by object and it doesn't defy its meaning. OOPs concept is philosophical you follow the rule so that you can have strategy how write code effectively.  ( 3 min )

Why splitting your codebase too early can quietly destroy your team’s velocity — and what to do instead. In a startup, your survival depends on how quickly you can iterate, ship features, and deliver value to end-users. This is where the foundational architecture of your startup plays a big role; additionally, things like your tech stack and choice of programming language directly affect your team’s velocity. The wrong architecture, especially premature microservices, can substantially hurt productivity and contribute to missed goals in delivering software. I've had this experience when working on greenfield projects for early-stage startups, where questionable decisions were made in terms of software architecture that led to half-finished services and brittle, over-engineered and broken l…  ( 14 min )

^ in Object Initializers The ^ operator (read as "from the end") has been part of C# since version 8, allowing developers to easily access elements from the end of collections: int last = myArray[^1]; // Last element However, until C# 13, you couldn’t use ^ inside object initializers. This restriction has now been lifted, giving developers more expressive and compact ways to initialize collections directly. Let’s explore how this change improves array initialization syntax and simplifies common patterns. Prior to C# 13: var countdown = new TimerRemaining(); countdown.buffer[^1] = 0; // Valid But you could not write: var countdown = new TimerRemaining { buffer = { [^1] = 0 } // ❌ Compiler error before C# 13 }; Now, this syntax is fully supported. ^ in Initializers public class…  ( 4 min )

In modern C#, method groups — collections of methods with the same name but different signatures — are frequently used in scenarios like: Passing methods as delegates LINQ projections Action, Func assignments Method references in event subscriptions C# 13+ introduces an important enhancement in how the compiler handles these method groups by optimizing the resolution of a natural type (i.e., an expected delegate type) for a method group. Let’s explore what changed, how it affects overload resolution, and what it means for you as a C# expert. A method group is a set of method overloads identified by a shared name: void Log(string message) { ... } void Log(string message, LogLevel level) { ... } Calling Log without parentheses creates a method group, which the compiler tries to match to…  ( 4 min )

Why this matters? The core essence of Computer Science at the lowest level is manipulating data through logical operations to perform calculations and every single CS related company in the world, is racing to do more of it, in a shorter amount of time. The challenge? Scale! As datasets grow linearly, the computational resources needed frequently grow exponentially or at least non-linearly. For example, many graph algorithms and machine learning operations scale as O(n²) or worse with data size. A seemingly modest 10x increase in data can suddenly demand 100x or 1000x more computation. This exponential scaling wall creates enormous technical and economic pressure on companies handling large datasets — forcing innovations in algorithms, hardware architectures, and distributed systems just…  ( 7 min )

When storing a segment of serialized data of uncertain length in a database, many people design the field as VARCHAR(2000) in the table schema. But if the length is uncertain, why not use the TEXT type instead? Some say: TEXT affects query performance. Is that really the reason? This article will explore that: TEXT is a variable-length data type in MySQL, including TINYTEXT, TEXT, MEDIUMTEXT, and LONGTEXT. They are typically used to store large amounts of textual data, with the following storage limits: TINYTEXT: 0 - 255 bytes TEXT: 0 - 65,535 bytes MEDIUMTEXT: 0 - 16,777,215 bytes LONGTEXT: 0 - 4,294,967,295 bytes Each BLOB or TEXT value is represented internally by a separately allocated object, whereas other data types have storage space allocated once per column when the table is opene…  ( 4 min )

Not long ago, “AI in SaaS” felt like a buzzword, a chatbot here, some automation there. But in 2025, it’s clear: I recently made a quick YouTube Short that summarizes this shift in just 60 seconds. But I wanted to share a bit more context with the dev.to community, because many of us are building this future. Here’s what’s really changing: AI handles what used to be the boring, manual work, form filling, task assignment, ticket tagging, report generation. Not only is it faster, but it actually lets teams focus on solving real problems. AI isn’t just reacting anymore, it’s learning. We’re seeing apps that adjust to each user: what they click, when they drop off, which features they ignore. AI then reshapes the experience in real time. Feels like magic (but it's models). Whether it’s predicting churn, forecasting demand, or recommending next steps, smart SaaS tools are becoming proactive. This gives users (and product teams) a serious advantage. At ClickIT, we’ve been working with startups and mid-size companies to integrate this kind of AI into their SaaS platforms. It’s wild how quickly things evolve once AI becomes part of your architecture, especially when the goal is to scale fast without losing control. Here’s the video I mentioned, just 60 seconds, made to spark ideas: How AI Is Revolutionizing SaaS in 2025 Are you already integrating AI into your product? If not ❌ — What’s holding you back? And if yes ✅ — What has surprised you the most? Would love to hear how other devs, founders, and engineers here are approaching the AI shift in SaaS.  ( 3 min )

Swapping variables is one of the most basic procedures that are done in programming. The first approach -and usually the most used by far- is to swap using a third variable, commonly named temporal variable. I'm sure you have seen it already. void swap(int* a, int* b) { int temp = *b *b = *a *a = temp } Yeah, that's a lot of pointers for explaining a swap. Blame C, not me 😒. Either way the process is the same in all languages: The value of variable b is stored in a temporal variable The value of variable a is stored in b The value stored in the temporal variable is moved to a I don't think it is necessary to say that the same process can be done replacing a with b and b with a But what if I told you that there's a way to swap values without using extra memory for a third vari…  ( 5 min )

Data Remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously written data to be recovered. Data remanence may make inadvertent disclosure of sensitive information possible should the storage media be released into an uncontrolled environment (e.g., thrown in the bin (trash) or lost). Various techniques have been developed to counter data remanence. These techniques are classified as clearing, purging/sanitizing, or destruction. Specific methods include overwriti…  ( 3 min )

Problem 1: Check for a Toeplitz Matrix Problem: You are given an n x n square matrix. Write a function is_toeplitz(matrix) that checks whether the matrix is a Toeplitz matrix. A Toeplitz matrix is one where every descending diagonal from top-left to bottom-right (↘️) contains the same elements. Consider this matrix: 6 7 8 4 6 7 1 4 6 The diagonals are: [1], [4, 4], [6, 6, 6], [7, 7], [8] All elements in each diagonal are equal — so this is a Toeplitz matrix ✅. To check if a matrix is Toeplitz: Loop through each element in the matrix (excluding the last row and column). For each element, compare it with the one diagonally down-right from it. If any of those pairs don’t match, return False. If the loop completes without mismatches, return True. from typing import List def is_toeplitz(matrix: List[List[int]]) -> bool: n = len(matrix) for i in range(n): for j in range(n): if i + 1 < n and j + 1 < n: if matrix[i][j] != matrix[i + 1][j + 1]: return False return True matrix = [ [6, 7, 8], [4, 6, 7], [1, 4, 6] ] print(is_toeplitz(matrix)) # Output: True  ( 3 min )

Las empresas de gran escala operan con arquitecturas distribuidas que involucran: Múltiples centros de datos Servicios en la nube (multi-cloud o híbridos) Miles de dispositivos y usuarios conectados Requisitos legales y normativos (como ISO 27001, GDPR, HIPAA) Esto genera una superficie de ataque enorme y puntos débiles como credenciales expuestas, errores de configuración, y tráfico interno mal segmentado. Ransomware dirigido a infraestructura crítica Phishing interno y comprometimiento de cuentas privilegiadas Ataques DDoS a servidores expuestos Exfiltración de datos a través de canales cifrados Abuso de servicios cloud mal configurados (como buckets S3 públicos) Zero Trust Architecture: no se confía ni en dispositivos internos sin validación. Segmentación de red dinámica: SDN y microsegmentación. Monitoreo continuo: SIEM y detección basada en comportamiento (UEBA). Respuestas automatizadas: SOAR y playbooks de contención.

O que é o Padrão Observer? O Observer é um padrão de projeto comportamental que define uma relação de dependência entre objetos, onde um objeto (o sujeito) notifica automaticamente outros objetos (os observadores) sempre que seu estado muda. Ele é muito útil quando várias partes do sistema precisam reagir a mudanças em um mesmo ponto. Esse padrão promove o desacoplamento entre quem emite o evento e quem reage a ele, permitindo que novos observadores sejam adicionados ou removidos em tempo de execução, sem alterar o sujeito. Em resumo, o Observer estabelece um mecanismo de notificação automática, garantindo que todos os interessados estejam atualizados sempre que algo importante acontece. As classes que devem reagir a mudanças se inscrevem no sujeito responsável por emitir essas mudanças. A classe principal recebe os observadores via o método addObserver(), registrando as implementações interessadas em ser notificadas. O método newStockData() executa a ação principal e, em seguida, notifica todos os observadores inscritos, permitindo que eles executem suas responsabilidades de forma independente. Assim caso surja uma demanda de adicionar uma nova açãoao newStockData, você não precisaria modificar a classe  ( 3 min )

Introduction In this tutorial, we will explore how to effectively join the AccountingEntity and PeriodEntity when using Entity Framework Core in C#. The aim is to filter AccountingEntity based on a Group parameter while ensuring the Period property is properly initialized from the Periods table. This is a common scenario when dealing with related database tables in a fixed schema situation. Understanding the Relationship We are working with two tables: periods and accounting. The primary key in the periods table is a combination of group and id, while the accounting table has periodid that corresponds to id in periods. The relationship between these tables is established by matching accounting.periodid with periods.id, although no foreign key is defined in the schema. Correcting the Entity…  ( 4 min )

I had read about regular expressions and thought of writing a blog on this. I will try to cover as much as possible. Let's start with the basic definition. A regular expression (also “regexp”, or just “reg”) consists of a pattern and optional flags. In short, it is the method of matching strings to a pattern. Two syntaxes can be used to create a regular expression. const regexp = new RegExp("pattern","flags"); OR const regexp = /pattern/; //without flags const regexp = /pattern/flags; Regex should be written within forward-slashes /..../. These slashes play the same role as quotes in strings. The main difference between the syntaxes is that when the regular expression remains constant, use a pattern with a slash for better performance, but if the regular expression is changing, or you d…  ( 4 min )

If you've ever tried to install a Python package and encountered the 'externally-managed-environment' error, you're not alone. This commonly occurs when using pip in environments where your Python installation is managed by your operating system's package manager. In this guide, we'll explore why this issue happens and how to resolve it successfully using virtual environments or other methods. Understanding the 'externally-managed-environment' Error This error message appears when you try to use pip to install packages, but your operating system has set restrictions on modifying the default Python environment. Essentially, your OS manages Python installations, and direct installations using pip can lead to an unstable system if packages conflict or if dependencies are missing in the system…  ( 4 min )

I know we all love JavaScript. We all love TypeScript, React, etc... But sometimes don't you feel that you want to try something else? Something new? I want to introduce a different way to build modern web apps using WebAssembly. It will bring you a next level of frontend world. Mostly, I use Rust alongside WebAssembly because it enables me to utilize a strongly static type system and efficient memory management system that JavaScript and TypeScript lack of.

When it comes to building multi-module Java projects with Maven, many developers encounter longer build times that hinder efficiency. If you’re struggling with a build process that takes around 40 seconds, even with multi-threaded builds using -T and -C flags, you’re not alone. With Maven 3.2.3, optimizing build performance can seem challenging, but there are strategies to help speed things up without compromising your workflow. Understanding Maven Build Performance Maven build times can be affected by numerous factors, including: Dependency Management: The way dependencies are resolved and downloaded can impact build times. For example, if your project relies on a large number of external dependencies, Maven spends time fetching them. Build Lifecycle: The default build lifecycle consists …  ( 5 min )

Linear search is a simple algorithm that checks each element in a list sequentially until the target value is found or the list ends. Start from the first element. Compare each element with the target value. If found, return its index. If not found after checking all elements, return -1. package com.Example; break; } else { System.out.println("Not occur"); } } sc.close(); } } Time & Space Complexity Time Complexity: O(n) (Worst case: checks all elements). Space Complexity: O(1) (No extra space needed). When to Use Linear Search? ✔ Small datasets. Simple but inefficient for large datasets. Works on any list (sorted or unsorted). Easy to implement in Java. For faster searches, consider Binary Search (O(log n)) if the list is sorted. 🚀  ( 3 min )

If you’re using Redis in a Node.js application — especially in production — reliability isn’t optional. A bad connection strategy can lead to memory leaks, crashes, or endless retry loops. In this blog, I’ll show you how I built a resilient Redis integration in Express.js using ioredis, lazy loading, and a circuit breaker with opossum. At first, I used the classic approach: const redis = new Redis(); // 🤷‍♂️ at the top level But I quickly ran into issues: Connection errors on startup if Redis wasn’t ready. Too many retry attempts without a proper limit. No fallback strategy during Redis downtime. So, I rebuilt the entire integration with three key ideas: ✅ Lazy Loading instead of connecting at startup, I created a singleton getter that initializes Redis on first use: import Redis from "…  ( 6 min )

Functional programming has gained traction in modern development due to its ability to produce more predictable, modular, and testable code. In this post, we explore four fundamental principles: immutability, function composition, pure functions, and arrow functions. Immutability means that once a value is created, it cannot be changed. Instead of mutating data, we return new versions with the desired updates. ✅ Why is it useful? Prevents unpredictable side effects Easier debugging and testing Ideal for concurrent environments (like React or Redux) ❌ Mutable example: const user = { name: 'Alice', age: 25 }; user.age = 26; // Mutation ✅ Immutable example: const user = { name: 'Alice', age: 25 }; const updatedUser = { ...user, age: 26 }; // New copy with changes Function composition means …  ( 4 min )

For over 15 years, the smartphone has been the centre of our digital universe. It’s the screen we stare at, the tool we work on, the device we reach for instinctively. But look a little closer — and you’ll start to see the shift. We’re entering the post-smartphone era. Not with a bang, but through quiet disruption. And it’s already on your body. The Rise of the Wearable Web I wear a smartwatch that tracks my health, receives notifications, and lets me respond instantly. Samsung just launched a smart ring — one more layer of ambient computing wrapped around our daily lives. And of course, I can speak to an AI assistant and get intelligent, contextual responses without touching a screen. This is no longer sci-fi — this is now. A New Hub: The Invisible Puck Imagine: A tiny 5G/6G puck lives in your backpack Your glasses are your screen Your ring is your security token Your watch handles notifications and health Voice becomes your primary interface AI becomes your operating system No more swiping. No more “app folders”. No more trying to type with your thumb while walking. Screens Are Becoming Optional Even today, I can ask my glasses to play a song, call someone, or answer a question — all without touching a smartphone. I don’t need a “phone” to live connected. I just need smart inputs, wearable endpoints, and a cloud intelligence layer. What This Means App developers will have to rethink interaction: conversational, contextual, multi-device. Privacy, identity, and edge computing will take centre stage — because the phone as a walled garden will be gone. We’ll be more present — or at least, less distracted by rectangles. The Debate Begins Will we embrace ambient computing — or push back against losing physical control? One thing’s clear: the era of staring at your hand all day is giving way to something new. So here’s the question: Would you give up your phone if you could wear the web instead?  ( 4 min )

When working with TensorFlow.js, it's not uncommon to encounter errors related to tensor dimensions. One such error, as you've described, occurs when the expected dimensions of your model's output do not match the shape of the provided labels (targets) during training. Let's explore this issue further and provide solutions to resolve it. Understanding the Error The error message you received states: Error when checking target: expected dense_Dense2 to have 2 dimension(s) but got array with shape 2,5,2. This indicates that the output layer of your model was expecting a different shape for its targets than what it received. In simpler terms, the model's structure is out of sync with your training data's shape. Why This Happens In your model, the last dense layer is configured to output a 5-d…  ( 5 min )

There is a lot of noise on "MCP (Model Context Protocol)" and as someone at the forefront of technology we have no choice but to follow it up. Often, despite the initial waryneess the AI hype drains my energy, some careful study turns out to generate useful insights. MCP is a protocol, but the majority of the protocol work is already done when OpenAI annouced tool use for ChatGPT. What matters now is the standardization process of the publisher of MCP, i.e. Anthropic (Creator of Claude models and tools). In addition to the publications, MCP offers server/client implementations for C#, Python, JavaScript - and that can speed up and streamline the development process. Whenever an experienced developers sees the tool use API (e.g. from OpenAI), they will immediately think of automatic code generation and streamline and tool definition process, and develop custom tooling to define those tools and serve those tools. MCP offers a ready-to-use (language-of-your-choice) implementation for a stated server. But here is a critical observation: does MCP has anything to do with AI/LLM at all? It's reinforcing what should have already been done: making systems reflective and accessible from an outside system. Here is a pun: it requires existing systems to be more reasonable (also see Forbes article on GEO). Traditionally, when a software is developed if the original developer doesn't expose useful APIs then power users have no obvious way of automating it, except through the more hacky GUI automation route. Now with the pressure of AI, vendors have to expose useful interface. LLM with its natural language nature makes it easiser for them to pick, compared to picking a more specific scripting language (or rest API), especially when the MCP server/client framework is stated and uses JsonRPC. Also see: Medium post on "Some Reflections on MCP".  ( 3 min )

TDD and BDD Explained TDD = Test-Driven Development BDD = Behavior-Driven Development BDD is all about the following mindset: Do not test code. Test behavior. So it's a shift of the testing mindset.

Introduction In my journey through C++17, I stumbled upon the std::byte type and discovered some perplexing behavior that left me scratching my head. The main question is whether this behavior is intended by the C++ standards or if it's a quirk due to the compiler or operating system I am using. Understanding std::byte The std::byte type introduced in C++17 is designed to encapsulate the idea of a byte without its conventional mathematical interpretations. Unlike integers, std::byte doesn't implicitly convert to numeric types, which can lead to some interesting outcomes when performing operations with it. In the example I encountered, I defined a std::byte variable and used std::to_integer to convert it to different integer types. The Code Example Here’s the code snippet that raised my que…  ( 5 min )

If you're working with MATLAB’s built-in lsqcurvefit function to fit a series of irregular Lorentzian peaks, you might have come across the challenge of correctly defining your custom model function. Your goal is to ensure that MATLAB can interact with your function without errors, particularly the one stating 'function is undefined for arguments of type "double".' In this article, we'll explore how to properly set up the FUN parameter in lsqcurvefit and ensure your data is fit appropriately. Understanding lsqcurvefit lsqcurvefit is designed to solve curve fitting problems by minimizing the sum of squares of nonlinear functions. It requires several inputs, including an initial guess for the parameters, the data points you want to fit, and a function that calculates the model predictions.…  ( 4 min )

Introduction If you’ve landed on this article, you’re probably wondering: “What’s all this MCP stuff about?” and “Why is it getting so much hype lately?” Or maybe you already have an idea and just want to build your own MCP server to let LLMs interact with your tools. So, let’s quickly answer the basics to get on the same page and then jump right into building your first MCP Server. At this point you probably know what MCP is, but if you don’t, no worries - I’ve got you covered. MCP was introduced last year by Anthropic (the company behind Claude) and stands for Model Context Protocol It might sound complex at first, but it’s actually quite simple. MCP is a way to let LLMs (Large Language Models) interact with tools in a open standard way, allowing them to get context from different data…  ( 7 min )

Ever wondered what keeps your online experience smooth, secure, and sometimes even anonymous? Meet the HTTP proxy — a powerful intermediary that stands between your device and the internet. At its core, an HTTP proxy processes and forwards your HTTP requests, essentially acting as a gateway. Instead of your browser connecting directly to a website, the proxy server does the job on your behalf, masking your IP address and offering a range of added benefits. To really grasp what an HTTP proxy does, you need to understand its building blocks. Hypertext Transfer Protocol (HTTP) is the standard protocol for transferring data online — everything from browsing websites to interacting with web applications. While HTTP operates over TCP/IP and Google's QUIC protocol, it lacks built-in encryption. I…  ( 5 min )

When dealing with variable length arrays (VLAs) in C, a common concern arises regarding the lifetime of such arrays when a function call is made after their declaration. According to the C17 final draft document N2176, the lifetime of an object, including a VLA, extends from its declaration until the program execution leaves the scope of that declaration. This statement often leads to questions about whether calling a function immediately after declaring a VLA results in ending its lifetime. To clarify, let's first understand what a variable length array is and its properties. A VLA is a type of array in C where the size is determined at runtime rather than at compile-time. This feature makes VLAs quite flexible for situations where the size of data is not known until the program runs. Und…  ( 5 min )

I am not new to rust. I have dabbled in axum, tonic, bevy and ratatui for some personal and work projects as well. Even then when someone asked me to write a Binary Search Tree(BST) in rust, I got scared. I didn't express this at the time but it kept bugging me inside. Anyway later on whenever I used to get time I used to ask AI tools to help me teach rust and write a BST specifically. I used Gemini and ChatGPT and both gave solutions as well. I could understand their code but still couldn't understand how they got there. They used Rc, RefCell etc. which I understand theoretically but never understood when and how to use it properly. After I didn't feel satisfied using AI answers I thought let me just read code. Rust actually provides a BST in standard library, you can find it here. Its ve…  ( 5 min )

This tutorial was originally published on IBM Developer by Markus Eisele Quarkus is a Kubernetes-native Java stack tailored for GraalVM and OpenJDK HotSpot. Quarkus offers incredibly fast boot times, low RSS memory consumption, and a fantastic developer experience with features like live coding. This quick start guide gets you up and running with Quarkus on macOS, including necessary tools. You will build a basic database application using Quarkus, Java 17, PostgreSQL, and Hibernate ORM Panache. While Hibernate ORM is the standard, powerful Jakarta Persistence implementation capable of complex mappings, it doesn't always make the most common tasks trivial. Hibernate ORM with Panache is Quarkus's solution to this, focusing specifically on making your data entities and repositories simple, straightforward, and fun to write by reducing boilerplate code for common persistence operations. We'll use standard macOS tools and package managers where possible. These are the essential tools you'll need to complete this tutorial: - Podman - SDKMAN - Java 17 - Quarkus CLI - Maven Optionally, you can also install a code editor. Quarkus integrates seamlessly with containers, especially for development services like databases and other sytems. Podman is a daemonless container engine alternative to Docker. On Mac, each Podman machine is backed by a virtual machine. Once installed, the podman command can be run directly from the Unix shell in Terminal, where it remotely communicates with the podman service running in the Machine VM. It is almost transparent in usage to Docker and easy to use for development. Install Podman. Find the latest Podman release on the GitHub Release page, and download the binary for your system architecture. At the time of writing, the latest release was v5.4.1. Install either the unversal pkg installer or the arm or amd version. Continue reading on IBM Developer  ( 3 min )

AWS Lambda is a go-to service for building scalable, event-driven applications — but with great (serverless) power comes great responsibility. Here are some practical security best practices to keep your Lambda functions secure in 2025: ✅ 1. Use the Principle of Least Privilege Create dedicated IAM roles for each Lambda function. Grant only the permissions required for that function to operate. Use IAM policies with explicit allow/deny for tighter control. 🔐 2. Secure Environment Variables Instead: Use AWS Secrets Manager or SSM Parameter Store to securely manage credentials, API keys, and tokens. Access them during function runtime using IAM roles. 🌐 3. VPC Integration for Sensitive Resources Place it inside a VPC for better network isolation. Use private subnets with minimal internet exposure. Attach VPC endpoints for secure AWS service access. 📊 4. Monitor and Log Everything Amazon CloudWatch Logs for tracking function output and errors. CloudWatch Metrics to monitor: Invocation counts Duration Throttles and errors Optionally, integrate with AWS X-Ray for tracing. 📦 5. Enable Versioning and Aliases Use Lambda versioning to avoid overwriting stable code. Use aliases (like dev, prod) to route traffic between versions easily. Helps in rollbacks and gradual deployments. 🚀 Get Started Start applying these best practices today to make your AWS Lambda functions secure, resilient, and production-ready in 2025.  ( 3 min )

But a quiet revolution is underway. The most insightful minds in AI are now arguing that how we build and deploy AI is far more critical than what it can do. The next wave isn’t about replacing us; it’s about amplifying the uniquely human qualities of reasoning, ethical judgment, and contextual understanding – a conscious partnership designed for symbiotic outcomes. This isn’t simply a technical challenge; it’s a fundamental re-evaluation of our relationship with intelligence itself. The early narrative of AI was dominated by efficiency. Faster data processing, more accurate predictions, lower costs. T…  ( 7 min )

How many times have you seen someone build a beautiful MVP with all the cloud bells and whistles… only for it to flop? The product had everything. Lambda functions are buzzing. API Gateway routes are neatly mapped out. Cognito user pools are locked down. Files in S3, served globally via CloudFront. Data in DynamoDB. Logs in CloudWatch. IAM policies are crafted like a government document. The architecture diagram looked like a subway map during rush hour. And yet, no one used it. Zero traffic. Zero users. Zero impact. The hard truth? You don’t need AWS to build something users love. There’s a subtle poison running through the modern indie dev and startup ecosystem: overengineering. It usually starts innocently. You read a few posts on Hacker News. Watch a couple of YouTube videos from cloud…  ( 6 min )

I Just Deployed My First App with GitHub Actions! Here are 6 things I wish I knew earlier 🧵 Setting up CI/CD for the first time can feel like a maze — especially when you’re excited to automate but aren’t sure what bumps are waiting along the way. After deploying my Laravel API app using GitHub Actions, here are 6 key lessons that apply to any tech stack. CI/CD Isn’t Just About Automation — It’s About Resilience The goal of CI/CD isn’t just “automatic deployments.” It’s about building confidence in your deployments and being ready when things go wrong. Set up your pipeline to be predictable, repeatable, and easy to debug — because someday, it will break. ✅ Automate to recover, not just to deploy. Don't Cache Config Before .env Is Ready If your pipeline runs php artisan config:cache (o…  ( 4 min )

A Complete Understanding of Basis Path Testing We have repeatedly emphasized the importance and necessity of software testing during development and real-life runtime cycles. Path testing, a key process in the testing procedure, is often used in designing test cases. It is a structural testing technique that uses the program’s source code to identify every possible executable path. This helps detect errors and bugs along defined program routes. In this article, we will explore a specific approach to path testing known as the Basis Path Test and its nuances. Basis path testing often referred to as structured testing, is a white box testing method (testing the software’s internal programming, structure, etc.) used to design test cases. It is performed based on the control-flow graph or log…  ( 5 min )

Creating a well-structured grid layout in HTML can be a vital part of web development. You might be looking for ways to implement a grid layout while ensuring that each row is visually distinct by having full row borders, rather than just borders around individual cells. In this article, we will explore how to achieve this effectively. Understanding the Grid Layout The CSS Grid Layout is a powerful tool that enables developers to create complex web layouts with ease. The problem you've encountered arises when attempting to give a clear separation between rows using borders without affecting the individual cells. Instead of applying borders to each cell, we need a different approach to make the entire row's border visibly distinct. A traditional method of creating a grid is through the use …  ( 4 min )

Detecting mouse events in a terminal interface using ncurses can initially seem challenging, especially when you want to execute a function continuously while a button is held down. In this article, we'll discuss how to leverage ncurses for mouse event handling in C++, specifically focusing on how to detect whether the left mouse button is held down and then call a function like foo() repeatedly until the button is released. Understanding Mouse Events with ncurses The ncurses library provides support for mouse events, which allows developers to create interactive console applications. When working with mouse events in ncurses, we mainly use the MEVENT structure to capture mouse input. As you mentioned, you can use event.bstate & BUTTON1_PRESSED to check when the left mouse button is presse…  ( 5 min )

AI has been getting a lot of attention lately—and yeah, some of the buzz is overhyped, but there’s also something real going on. From my own experience as an engineering manager, I’ve seen how AI can free up time, speed up prototyping, and help devs focus more on what they actually enjoy doing—solving problems, shipping great products, learning new stuff. I get that some people are worried AI will take their jobs. Honestly, I don’t think that’s the right question. It’s less about “Will AI replace me?” and more about “How can I use AI to level up and stay ahead?” Here are five ways I’ve seen AI help software engineers do just that. You know that feeling when your calendar's a mess, you’ve got three tickets on the go, and you're still getting pinged every five minutes? A few of my team membe…  ( 5 min )

(with apologies to Neil Young) tl;dr - a story is told about how the author tests a module against a third-party web API when that service is not always available and without leaking sensitive authentication tokens You find yourself to be an aspiring CPAN author of a web API and as a righteous follower of Test Driven Development you want to write tests to verify that your API works as advertised. Testing is a big part of Perl culture, so a skeleton module usually comes with a t/ directory to hold your tests. Once uploaded to CPAN, the CPAN Testing Service will run your tests on every OS and version of Perl possible, but you shouldn't require an active network connection on either end. After all, has your API failed because the end service is down for annual maintenance or the local interne…  ( 5 min )

Introduction When integrating Google OAuth for authentication in your application, you might encounter various errors. One common issue is the ERROR 403: Google disallowed user agent, especially if your code works perfectly on Android but fails on iPhone. This error message usually indicates that Google is rejecting the request due to the user agent string that your app is sending. Let's explore why this happens and how to fix it. Understanding the Issue The ERROR 403: Google disallowed user agent typically occurs when Google’s servers identify an untrusted or unsupported user agent accessing their OAuth service. User agents represent the application type, operating system, vendor, and version of the browser, and if the string does not match Google's expectations or security policies, the …  ( 5 min )

As a softwar developer, choosing the right language and tools can make a huge difference in how efficiently you build, maintain, and scale applications. While Node.js is widely adopted in the backend world, I personally prefer Go (Golang) for several key reasons. Here's why. Go is a compiled language with built-in support for concurrency through goroutines and channels. Whether it's handling multiple HTTP requests or processing data-heavy tasks, Go offers consistent and high performance with minimal memory overhead. Its lightweight concurrency model is often simpler and more efficient than JavaScript’s event loop and async/await system. Go is statically typed, which helps catch errors early during compilation. In my experience, this leads to more robust code and reduces the kind of silent …  ( 4 min )

How We Built Delta Executor: Mobile-First Roblox Script Execution Roblox's scripting ecosystem has exploded in recent years — and so has the need for tools that empower developers to understand, test, and interact with Lua-based environments. At DeltaDevs, we created Delta Executor, a performance-first, cross-platform executor tailored for Roblox scripts on Android and iOS. Many tools in the Roblox ecosystem are outdated, unsupported, or overly complex for mobile users. Delta Executor solves that with: Script execution that’s stable across devices A secure framework with memory-safe design Keyless access for paid users (and fair key-based access for free users) Smooth compatibility across Android, iOS, and emulators for PC We built it from the ground up to handle the latest anti-cheat systems Roblox introduced in 2025. Here’s how we bypassed them. -- Delta Executor Example print("Hello from Delta Executor on Mobile!") You can load, run, and debug scripts just like this on mobile devices using our tool. Full support for popular script libraries and obfuscation is built in. While built for mobile-first use, Delta Executor also runs on Windows using emulators like BlueStacks or LDPlayer. Want to see how it works? Visit our Executor Overview Page. We're also opening up SDK access for vetted contributors and curious reverse engineers. Apply at deltadevs.net/developers We built Delta Executor with security transparency at the core. If you've seen antivirus warnings, you're not alone — many executors trigger false positives. Here's why. Official Website FAQs Script Submission Fix Guide: Executor Not Opening Delta Executor is more than an exploit tool — it’s a research sandbox for scripters, hobbyists, and curious minds working within the Roblox engine. We hope this adds value to others building tools around Lua, mobile execution environments, and anti-cheat resistance. Got thoughts? Drop your feedback or reach us via our Discord.  ( 3 min )

In tech, we’re wired for growth—more velocity, more releases, more impact, more headcount. But lately, I’ve been asking myself: Where does it stop? I’ve led high-performing teams, shipped at scale, climbed the ladder. But with each new role, I noticed a pattern—what looked like “success” on paper often came with hidden trade-offs: less time with family, more stress, fewer pauses to reflect. We’re told to aim for the next title, the bigger compensation package, the unicorn IPO—as if each step up will quiet the internal noise. But it doesn’t. Even at the top, many feel like they’re still chasing something just out of reach. And here’s the kicker: when wealth and power concentrate, whether in tech or society, others get squeezed. I’ve seen brilliant engineers burn out, not because they weren’t good enough—but because the system kept telling them they had to want more. But what if the real clarity doesn’t come from achieving more—but from needing less? Less chaos. I’ve found meaning in simpler things—mentoring a junior dev, walking outside between meetings, unplugging for dinner with my kids. These aren’t productivity hacks. They’re sanity savers. Because underneath the frameworks and sprint goals, we’re just part of something bigger—organic, changing, deeply human. The atoms in our bodies? They were once stars. Literally. We are nature. And like nature, we’re not meant to scale infinitely. So here’s a quiet question I’m sitting with—and maybe you should, too: 🔍 Is your pursuit of “more” giving you peace—or quietly taking it away?  ( 3 min )

📍 Problem description You have two applications: App 1 → deployed on Server A, port 80 App 2 → deployed on Server B, port 80 When you try to configure both behind SafeLine WAF, you get the error: Duplicate applications detected on port 80: * The reason for this error is: SafeLine allows only one listener on port 80 on the frontend. ⸻ ✅ How to solve it Since SafeLine currently does not support path-based routing, the only supported solution is domain-based routing. ⸻ Use different domain names (recommended) For example: App 1 → app1.example.com → Server A:80 App 2 → app2.example.com → Server B:80 In SafeLine: Configure one listener on port 80 Set routing rules based on the Host header (domain name) to forward traffic to the correct backend server. This way, SafeLine knows exactly which application the request is meant for. ⸻ ⚠️ Why you can’t use multiple port 80 listeners or path-based routing SafeLine can only bind to port 80 once on the frontend. Multiple port 80 listeners will always result in a duplicate port error. Path-based routing (/app1, /app2) is currently not supported in SafeLine. ⸻ 🚀 Summary recommendation ✅ Use different domain names and set up Host-based routing in SafeLine. ⸻ SafeLine Website: https://ly.safepoint.cloud/ShZAy9x https://github.com/chaitin/SafeLine https://discord.gg/dy3JT7dkmY  ( 3 min )

There is a 2-layer JSON string with multiple dynamic key values in the lower layer, excluding set/array types. {"Games": {"key1": "value1", "key2": value2,"key3":value3}} Now we need to transform the lower layer into a set of multiple layers. {"Games":{"AllGames":[{"key1":["value1"]},{"key2":["value2"]},{"key3":["value3"]}]}} SQL itself does not support multi-layer data, making it more difficult to express multi-layer sets, and the indirectly implemented code is very complex.

Welcome to the final part of our SafeLine WAF series! So far, you have set up SafeLine and configured it for your environment. Now, it’s time to test your protection, finalize your Docker installation if necessary, and troubleshoot any issues that may arise. This will help you maintain a robust and reliable WAF deployment. You can test the protection effectiveness either manually or automatically. Access your website using the parameters configured in SafeLine WAF: Open your browser and visit: http://: / The default protocol is HTTP; check the SSL option to use HTTPS. The hostname can be either the SafeLine IP or your website domain (make sure the domain resolves to SafeLine). The port is the one you configured in SafeLine for the site. If your website is not accessible, please refer to the Configuration Issues section. Try these URLs to simulate attacks and confirm SafeLine blocks them: SQL Injection: http://: /?id=1%20AND%201=1 XSS Attack: http://: /?html=alert(1) If SafeLine blocks these, you’ll see the attack prevented in your browser and logged in the dashboard. ✅ sudo yum update If you get errors like “Could not resolve host” or mirrorlist failures, add Alibaba Cloud repo: curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo sudo yum install -y yum-utils sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo sudo yum -y install docker-ce docker-ce-cli containerd.io sudo systemctl start docker If you get x509 certificate errors when pulling images, it’s likely a system time or certificate issue.

Now that we've confirmed Docker is installed and running (Part 1), let's test the setup by running a simple container. This will verify that Docker can successfully download images and run containers. The Hello World Container Docker offers a lightweight "hello-world" image specifically designed to test Docker installations. This minimal container confirms that: • The Docker client can connect to the Docker daemon. 1.Let's run this test container with the following command: docker run hello-world • Check if the hello-world image exists locally This message confirms that your Docker installation is working correctly. After running the hello-world container, let's check the list of containers on your system. The container we just ran has already exited, but we can still see it in the list of all containers. 2.To see all containers (including stopped ones), run: docker ps -a The -a flag shows all containers, including those that have stopped. Without this flag, docker ps would only show running containers. STATUS column shows "Exited (0)", which means the container completed its task and exited with a status code of 0 (indicating success). The hello-world image was downloaded to your local machine. Let's verify this by listing all Docker images: docker images This confirms that the hello-world image is stored locally on your system.

Most services — including social networks — offer APIs that allow third-party programs or tech-savvy users to perform actions that would normally be manual and tedious, all through code. Let’s imagine I’m blocking people on BlueSky, and I want to know if another account has blocked the same people as I have. I would need to: Retrieve my own block list Retrieve the block list of the other account And for each name, check if it's present in both lists. It’s not impossible to do — at least on BlueSky, since everything is public. But it’s a massive pain.

In today's fast-paced tech world, speed matters. But quality matters even more. No one wants to launch a product full of bugs or deliver a user experience that doesn't live up to expectations. That's where quality assurance (QA) comes in - not as a final check, but as an ongoing, strategic process that ensures everything runs smoothly from the start. One of the biggest mistakes companies make is putting off QA until later. By then, fixing issues becomes expensive and time-consuming. A robust QA process starts right from the planning stage. QA shouldn't be an island. Developers, designers, project managers, and QA engineers should work as a team. Communication is key. Clear documentation, shared expectations, and open feedback loops help avoid misunderstandings and missed bugs. You can't fix what you don't track. That's why a well-defined test plan is essential. It sets expectations, outlines goals, and defines what success looks like. Manual testing has its place, especially when it comes to exploratory testing or checking visual and UX elements. But automation is the backbone of a scalable QA process. Smoke tests Regression tests API testing Cross-browser checks Tools like Selenium, Cypress, or Playwright can help speed up the process. Don't overdo it with automation, though - maintaining flaky tests can slow down your team more than it helps. Pro tip: CI/CD integration Hook automated tests into your CI/CD pipeline. That way, every time new code is pushed out, it's tested instantly. Faster feedback = fewer issues in production.

Omit and Pick are some of the most loved utility types in TypeScript. They let you create new types by excluding or selecting specific properties from an existing type. union types, their behavior can be misleading - and in some cases, break your type expectations type Employee = { id: string name: string job_name: string } type Customer = { id: string name: string company: string } type Person = Employee | Customer ❌ Problem: Using Omit Directly type PersonWithoutId = Omit 🧨 Actual Result: type PersonWithoutId = { name: string } Only name survives. The fields job_name and company are lost. Why? not distributive over union types. It collapses the union into a common structure, then removes the property - resulting in a simplified, lossy type. ✅ Solution: DistributiveOmit We can fix this by explicitly distributing Omit across each union member: type DistributiveOmit = T extends any ? Omit : never type PersonWithoutId = DistributiveOmit ✅ Expected Result: type PersonWithoutId = | { name: string; job_name: string } | { name: string; company: string } 🧪 Same Fix for Pick type DistributivePick = T extends any ? Pick : never type BasicaPerson = DistributivePick 🧠 Summary Table  ( 3 min )

In the smoldering forges of Old Valyria, where data flows like wildfire and downtime is the true enemy, there sits a sovereign of steel and silicon—the MSP40. Forged in the fires of precision and armored against chaos, this managed Ethernet switch defends the Seven Realms of Industry 4.0 with the ruthlessness of Tywin Lannister and the foresight of Bran the Broken. Let us declare why this switch claims the Iron Throne of industrial IoT. Chapter 1: The Forge of Dragonstone MSP40 is no mere ironborn gadget. Tempered in the Foundries of Valyrian Steel, it wields powers unseen since the Age of Heroes: Dragonflame Resilience: Operates from -40°C to +85°C—hotter than Drogon’s breath, colder than the Night King’s touch. Why it shatters the old order: Legacy Switches: As reliable as Joffrey’s promises—crumbling under pressure. Chapter 2: The War of Five Ports The Battle of Blackwater Bay (Smart Factories): MSP40 commands robotic arms with the precision of Arya’s Needle, slashing downtime like Lannister soldiers. “Chaos isn’t a pit. It’s a 40% productivity gain,” it whispers. The Siege of Winterfell (Power Grids): Guards substations against EMP storms, steadfast as Brienne’s oath. “The North remembers… surge protection.” The Red Wedding (Traffic Systems): Halts data collisions at smart intersections, sparing cities from King’s Landing-level gridlock. “The network sends its regards.” The Words of House MSP40 Ports: 12 channels of fury—8 RJ45 knights and 4 SFP dragons. The Dragons of Innovation The Dark Threats Beyond the Wall Legacy Switches: Bloat like Robert Baratheon’s reign, guzzling budgets and sanity. The Prophecy of the Prince That Was Plugged In Epilogue: Winter is Here (And It’s Buffering) the MSP40 is to court chaos—a realm of molten slag and screaming CFOs.

The Remy-Linguini Dynamic If you haven't seen the movie, here's the gist: Remy is an incredible chef with all the know-how, but he's a rat, so no kitchen access. Linguini is a kitchen worker with full access but little cooking skill. Together, they form a symbiotic relationship: Remy hides under Linguini's hat and guides him on what tools to use and when. If a customer orders fries, Linguini might freeze, but Remy scopes out the kitchen, sees what's available, and gives step-by-step instructions: "Grab a knife and a cutting board. Now slice the potato." Then, Linguini executes the plan. Agentic systems work similarly.

You can unpack the iterable which has zero or more values to one or more variables as shown below: *The number of variables must match the number of values unless a variable uses *. v1, v2, v3 = [0, 1, 2] v1, v2, v3 = [0, 1] # ValueError: not enough values to unpack (expected 3, got 2) v1, v2, v3 = [0, 1, 2, 3] # ValueError: too many values to unpack (expected 3) *The one or more values with one or more commas(,) are a tuple. v1, v2, v3 = [0, 1, 2] v1, v2, v3 = range(0, 3) v1, v2, v3 = 0, 1, 2 # Tuple v1, v2, v3 = (0, 1, 2) print(v1, v2, v3) # 0 1 2 *By default, only keys are assigned to variables from a dictrionary same as using keys(). v1, v2, v3 = {"name":"John", "age":36, "gender":"Male"} v1, v2, v3 = {"name":"John", "age":36, "gender":"Male"}.keys() print(v1, v2, v3) # name age gender *values() can get only the values from a dictionary. v1, v2, v3 = {"name":"John", "age":36, "gender":"Male"}.values() print(v1, v2, v3) # John 36 Male *items() can get both the keys and values from a dictionary. v1, v2, v3 = {"name":"John", "age":36, "gender":"Male"}.items() print(v1, v2, v3) # ('name', 'John') ('age', 36) ('gender', 'Male') print(v1[0], v1[1], v2[0], v2[1], v3[0], v3[1]) # name John age 36 gender Male v1, v2, v3, v4, v5 = "Hello" print(v1, v2, v3, v4, v5) # H e l l o  ( 3 min )

Mobile Navigation Menu How To, for Web Applications This tutorial explains How to Create a Vertical Navigation Menu for Smartphones and Tablets Using CSS and JavaScript. Imagine a top horizontal bar in a smartphone. There is the menu icon at the right of the bar, and the logo at the left of the bar. When the icon is clicked, a vertical menu bar appears below the top bar, pushing the main document content downwards. When the icon is clicked again, the vertical menu bar disappears and the main document content rises up to its original placement. Do not confuse between a menu and a menu icon. A menu is a list of items. The list may be vertical or horizontal. For this tutorial, the list is vertical. The menu icon is a small button having three horizontal bars.

Originally written at pooyan.info Who is the author? Check out my profile on LinkedIn. Vendor lock-in refers to a situation where an organization becomes overly dependent on a specific vendor's products or services, making switching to alternatives costly, time-consuming, or technically difficult. Over the years, many companies have experienced frustration when trying to move away from large vendors like IBM, Microsoft, or Oracle due to contractual constraints, proprietary technologies, and sudden pricing changes. A recent example is VMware's acquisition by Broadcom, followed by significant pricing changes that disrupted many businesses. In startup environments, it's common to hear voices urging multi-cloud strategies or insisting on only using "cloud-agnostic" tools to avoid a potential l…  ( 7 min )

Introduction If you’ve ever encountered the no main manifest attribute error while trying to run a JAR file in Java, you’re not alone. This common issue arises when the JAR file lacks the necessary metadata to specify the entry point of your application. This article will guide you through understanding this error, configuring your pom.xml file correctly, and successfully packaging your Java application into a runnable JAR file. Understanding the Error When you package a Java application into a JAR file, the Java Runtime Environment (JRE) looks for a specific entry in the JAR's manifest file to understand where the main class is located. If this entry is missing, Java throws the no main manifest attribute error. This typically happens when the maven-jar-plugin isn't correctly configured in…  ( 5 min )

Leapcell: The Best of Serverless Web Hosting The Python code style guide is not set in stone. It evolves continuously with the development of the language. Some old conventions are gradually phased out, and new ones keep emerging. At the same time, many projects have their own coding style guides. When there are conflicts, the project-specific guides should be followed first. However, there is an important principle to keep in mind: "The stupid persistence in consistency is the monster of ignorance", which is a profound insight from Guido. Since code is often read more frequently than it is written, the core goal of the style guide is to improve code readability and keep all kinds of Python code consistent. As PEP20 says, "Readability counts". The style guide emphasizes consistency. While …  ( 10 min )

Today I need to find a suitable foundational library for video processing. FFMpegCore works for one-shot things but despite a fluent API, its interface is still too command line like. Here is what I found out: OpenCvSharp LibVLCSharp FFMediaToolkit Frames ✅ decode / encode ✅ (via callbacks) ❓ Audio ❌ ✅ decode / encode / mux ❓ Extra libs ~5 MB/platform +7 MB +7 MB Licence Apache‑2.0 LGPLv2.1 MIT Platforms Win / mac / Linux / Arm Win / mac / Linux / iOS / Android Win / mac / Linux LibVLCSharp seems more focused on directly displaying things (e.g. in Xamarine and WPF) instead of low-level API based processing; FFMediaToolkit, on the other hand, still depends on FFMPEG and can't avoid licensing issue. Eventually, I had to go with separate video + audio processing in favor of OpenCvSharp (it's Apache-2.0 by the way). Notice OpenCVSharp has some advantage over EmguCV for custom dev: OpenCvSharp Emgu.CV Licence Apache-2.0 (fully permissive) GPL v3 or commercial licence Interop model Pure P/Invoke (no C++/CLI), works on any .NET core runtime Historically C++/CLI wrapper (needs Windows for full feature set), .NET Standard P/Invoke layer added later NuGet size (native) 4–6 MB per RID (modular runtime packages) 30 MB + for the “opencv‑world” monolith, or 90 MB for emgucv‑runtime‑ubuntu GPU (CUDA) support Provided in separate OpenCvSharp4.runtime.dnn package Official CUDA builds, but Windows‑only binaries unless you compile yourself API surface ~1:1 with OpenCV C++ names (easy to port C++ samples) Thicker .NET façade (e.g. Image types), extra helpers Cross‑platform stability Actively tested on Windows / Linux / macOS / arm64 Windows the main focus; Linux/macOS possible with libopencv from distro or big runtime package Learning curve If you know OpenCV C++ you feel at home Higher‑level abstractions can be friendlier for newcomers Commercial support Community‑driven Paid licences & support available from Emgu CV, Inc.  ( 3 min )

"Just because it’s one database doesn’t mean it should act like one app." Managing multiple applications using a single database with multiple schemas sounds clean—until things start to break under load.

We had: 🧵 Microservices for modules like user-service, order-service, etc. 🗃️ All shared the same PostgreSQL DB using dedicated schemas (user_schema, order_schema, ...). 🪝 Each app pointed to the same datasource (JDBC URL), but with different search_path schema config. What we expected: Clean schema separation with easy analytics and joins. What we got: Connection leaks, poor connection pool behavior, and schema confusion. With one shared datasource and multiple apps hitting the DB simultaneously, connections kept tim…  ( 4 min )

Introduction Understanding memory allocation in Rust, especially heap allocation, is crucial for writing efficient and safe programs. A common point of confusion arises when working with stack and heap memory, as illustrated by discussions in the Rust community. There has been notable inquiry surrounding issues like stack overflow errors, which are often linked to how Rust manages memory. In this article, we will explore how Rust handles heap allocation and clarify why it behaves the way it does. What is Heap Allocation in Rust? Heap allocation in Rust occurs when we need to allocate memory dynamically, which is often necessary for larger data that cannot fit on the stack. The Rust programming language helps manage memory through a system of ownership, borrowing, and its smart pointers lik…  ( 5 min )

Semicolons were often added to the end of URLs, especially in r/Conservative summaries, and they became a part of the hyperlinks wrongly, making some of the hyperlinks unusable. I often randomly test the hyperlinks and they all worked, but I just realize that I only test the longest hyperlinks, because I think they are the ones more prone to hallucinations. I didn't find any hallucinations. But yesterday I clicked some of the simpler links of r/Conservative summaries and I got 30% of them not working. I panicked because I thought the hallucination caught me off guard, but then I realized all the links were real, but they each got an additional ";" attached to them, which was redundant. The links themselves were correct but the semicolons I used to declare the end of line was wrongly identified as part of the URLs. The fix was simple. I removed all redundant semicolons from all my current and previous output documents. I am really surprised of this bug because it affected so many links but it evaded my "random" sampling for so long, because I didn't test the rendered URL links very thoroughly, and I thought very long and complex links were at higher risks of hallucination, so I tested those a lot. Weird enough, those never had problems, but the shorter, simpler links did. I am very sorry for the potential confusion it might have created.  ( 3 min )

What to know: Lyn Alden says a weaker dollar is necessary for the US to stabilize its financial system. Bitcoin and gold are well-positioned to benefit from de-dollarization. Sovereign wealth funds and various nations are already increasing their Bitcoin exposure as the dollar’s global dominance starts to wane. The weakening of the US dollar (DXY) is no longer headline news. With mounting disruptions across the US economy, a declining greenback has become part of the backdrop. Since the start of 2025, the US Dollar Index has dropped 11%, now hovering around levels last seen in April 2022. Markets have largely responded with a shrug. After all, in times of deep restructuring, isn’t some dollar weakness to be expected? The trouble is, this might not be a temporary dip. The dollar’s slide…

Braden John Karony, the former CEO of crypto firm SafeMoon, made an out-of-court statement claiming innocence as his criminal trial began in New York. In a May 6 X post after court proceedings had likely ended for the day, Karony said he was innocent and “did not commit fraud” in response to media coverage of his trial. The former CEO, as well as SafeMoon creator Kyle Nagy and former chief technology officer Thomas Smith, were charged in 2023 for having allegedly “diverted and misappropriated millions of dollars’ worth” of the platform’s SFM token. According to reporting from the US District Court for the Eastern District of New York (EDNY) on May 6, Karony implied that Nagy, who reportedly fled to Russia after authorities filed charges, was responsible for some of the alleged fraud at Saf…

Binance-affiliated BNB Chain has rebounded after a period of stagnation in 2023 amid accelerating institutional and decentralized finance (DeFi) adoption.  During the past year, BNB Chain has benefited from multibillion-dollar inflows into DeFi, US exchange-traded funds (ETFs), and rising trading volume at affiliated centralized exchange (CEX) Binance.  Consequently, the blockchain network’s native BNB token (BNB) has emerged as among the market’s most resilient cryptocurrencies, surpassing all-time highs in the first quarter of 2025 even as the broader crypto market trended downward.  “This resilience isn't just about price action — strong fundamentals also back it,” Joao Wedson, CEO of investing analytics platform Alphractal, said in an April X post. “Binance has built a massive ecosyste…

Opinion by: Anurag Arjun, co-founder of Avail  On paper, SocialFi is a no-brainer. It promises to shift the balance of power in social media — giving people control over how their content and personal data are used and monetized. It even offers users a stake in the $200+ billion social media advertising market, a pie currently devoured almost entirely by giants like Meta. And yet, SocialFi platforms today feel more like digital ghost towns than the bustling hubs of Web2. Friend.tech, hailed as a breakout star in 2023, peaked at just 80,000 daily active users before falling below 10,000. What's holding SocialFi back? Why does it seem to be following Friend.tech's fade into obscurity rather than rising to rival Facebook's dominance? The harsh reality is that decentralized social networks hav…

Cryptocurrency miner Diversified Energy quietly vacated a natural gas-powered crypto mining site in Elk County, Pennsylvania, reportedly leaving behind unplugged wells and regulatory violations. The site, known as Longhorn Pad A, was revived in 2022 after sitting dormant for nearly a decade when Diversified began using it to fuel on-site generators powering cryptocurrency mining computers, according to a report by the Erie Times-News. Per the report, the operation was launched without obtaining an air quality permit from the Pennsylvania Department of Environmental Protection (DEP). Though the company was later granted the permit in December 2023, a March 2025 inspection revealed that Diversified had already removed the mining infrastructure.

Despite the $1.4 billion lost in the recent Bybit hack, crypto companies have not changed their approach to cybersecurity, according to Hacken CEO Dyma Budorin.  In an interview with Cointelegraph at the Token2049 event in Dubai, Budorin said the industry continues to rely on limited measures such as bug bounties and penetration tests, rather than implementing comprehensive, layered security strategies: “Most of the projects think, ‘Okay, we did pentests. That’s enough. Maybe bug bounty. That’s enough.’ It’s not enough.” He said that crypto companies must go beyond these isolated security measures and adopt more layered approaches similar to those of traditional industries. These include supply-chain security, operational security and blockchain-specific security assessments.  “In big Web2…

Key takeaways: Bitcoin must maintain above $95,000 to have a chance at retesting its $109,000 all-time high; failure to hold could lead to a deeper correction, crypto analysts warn. Several crypto analysts told Cointelegraph in March that Bitcoin may have a chance of reaching new all-time highs in June. The upcoming Federal Reserve decision on May 7 could influence Bitcoin’s price movement over the coming days.

The relationship between Gross Domestic Product (GDP) and stock market performance is a subject of considerable interest to economists, investors, and policy makers alike. GDP measures the total value of goods and services produced by a country, and it serves as an indicator of the health and growth of an economy. The stock market, on the other hand, reflects the collective value of publicly traded companies and serves as a platform for buying and selling shares. Both metrics are often used to gauge economic conditions, yet their relationship is more complex than a simple correlation. While there is a connection between GDP growth and stock market performance, this relationship is influenced by various factors, including investor sentiment, economic policies, and external events. In some c…  ( 7 min )

There was a time when software releases were slow and monolithic—but at least everything was in one place. Now, we move faster. But that speed? It comes at a cost. Today, we live in a world of microservices, APIs, and distributed everything. The architecture is elegant. The orchestration is powerful. But testing? That’s where things get tricky. As a quality engineering leader, I’ve seen firsthand how this complexity tests more than just code—it tests our assumptions about ownership, accountability, and what “done” really means. In a microservices ecosystem, a single user journey might hit a dozen services. Each is built, deployed, and owned by a different team. And while unit tests may pass with flying colors, it’s the integration points—those fragile handshakes between services—that often…  ( 4 min )

Introduction In Java, managing complex key structures dynamically is a common challenge, especially when dealing with API response times and performance issues. In your scenario, you're saving keys in a map formatted like Krishna/thota/date/x/y/z while supporting wildcard characters (*) to match various entries. However, this approach leads to performance overhead due to the necessity of comparing strings, which can be inefficient when handling over a million records. We’ll explore better data structures and solutions to enhance performance while allowing for the flexibility you need for matching. Understanding the Performance Issue You mentioned that your current implementation takes approximately 200 milliseconds when you have more than one million records. This degree of latency can aff…  ( 5 min )

When a small purple dragon leapt joyfully onto television screens in 1998, gaming felt simpler. Spyro's tale was charmingly clear-cut: dragons good, Gnorcs bad. Yet, as those early fans grew alongside the medium itself, uncomplicated childhood memories gave way to reflective curiosity. With maturity comes the realisation that even playful narratives can unwittingly reveal complex truths—sometimes challenging, always intriguing. Among Spyro's cast, no group invites this reconsideration quite like the Gnorcs. Originally depicted as brutish, green-skinned adversaries to vanquish without second thought, today they stir conversation far beyond simple nostalgia. Central to this renewed interrogation of Spyro's world is Gnasty Gnorc himself. Once an outright villain, his motivations now appear le…  ( 6 min )

Most teams spend hours documenting everything. Notion workspaces. Confluence pages. GitHub wikis. You name it. But here’s what happens: ☑️New hires still get stuck. ☑️Devs still ask questions that are, “Somewhere in the docs” and crucial context gets lost. This is the Documentation Paradox: The more you write, the harder it gets to find, trust, and maintain what actually matters. Conventional wisdom says, “Async teams need tons of docs!” But I’ll say: More docs often mean less clarity. Here’s why: First, there's the maintenance burden. Every line of documentation is a liability that needs updating as your codebase evolves. How many teams actually do that? Second, comprehensive documentation creates a false sense of security. Teams believe they're covered because it's in the docs somewhere. What you should do is treat documentation as a conversation, not an artifact. Use tools that make updating docs as easy as sending a message. Encourage annotations and questions directly in the documentation. And remember the 20/80 rule: 20% of your features generate 80% of questions. Focus your efforts there. The goal isn't to have everything documented – it's to have the right documentation that actually helps your team move faster. This is why every Rally session lives forever inside Jira No more sorting through old Slack threads. Every discussion stays tied to the task, so your team’s knowledge grows with the work—not in a dusty folder.  ( 3 min )

In C#, there isn't a built-in method equivalent to Ruby's humanize for turning strings into a more natural format, but you can create functions to achieve this easily. In this article, we'll explore how to convert strings while following the two scenarios provided in your request: changing capitalization and formatting string cases to appear more human-friendly. Understanding the Humanization Process When we discuss 'humanizing' a string, we're typically referring to text transformation that makes it easier for humans to read or understand. This can involve adjusting capitalization, changing the case, or formatting text to look more polished and readable. Unlike Ruby, where the humanize function applies well-defined transformations, C# requires us to craft our own methods. Implementing a S…  ( 4 min )

Introduction When working with Rust and Diesel, you may encounter various issues, especially when performing count queries. In this article, we'll examine a specific error that arises from executing a count query using Diesel with PostgreSQL. The error message states, 'the trait bound i32: FromSql is not satisfied'. This indicates a type mismatch in your query resolution. Understanding the Error The error is primarily triggered because the Diesel ORM expects a specific data type from the SQL count result. Typically, when using the count function in a SQL query, the result is of type BigInt in PostgreSQL, which corresponds to i64 in Rust. However, your code attempts to return the result as an i32, leading to the compile error. Step-by-Step Solution Changing Return Type to i64 Th…  ( 4 min )

When working with CodeIgniter, you might want to utilize its query builder feature for better performance and security. For instance, let's consider the SQL query: SELECT * FROM questions WHERE course_id = 13; This query retrieves all records from the 'questions' table where the course_id is equal to 13. However, using raw SQL queries in CodeIgniter, as shown below, can lead to issues: $query2 = $this->db->query('SELECT * FROM questions WHERE course_id = 13', false); Why is This Query Problematic? Using this method can lead to potential SQL injection vulnerabilities, and it's not as efficient as using the CodeIgniter Query Builder.

Sightful’s Spacetop for Windows is a $899 bundle (plus a $200/yr subscription after year one) that turns your compatible Intel-powered laptop and Xreal Air 2 Ultra smart glasses into a multi-monitor, spatial-computing workspace. Wired gave it a 9/10, praising its polished software, comfy glasses (with dimming for outdoor use) and the private, ultra-portable productivity it delivers—arguably edging out Apple’s Vision Pro at a fraction of the price. It’s not all sunshine, though: the setup looks a bit dorky, only works on select Intel CPUs for now, saps battery life in a hurry and the glasses’ field of view could be wider.

Greetings to all! In this article, we will talk about a rather unusual topic, information about which for some reason I did not find, although it is quite useful in modern JavaScript frameworks and libraries for creating user interfaces, because, in some cases, applying the concept can help speed up work with the DOM several times. The name is conditional, but the essence is important. The term "usual state" refers to data that is saved directly due to the state managers, or due to the internal functionality of the framework or library. An example of the state in Vue.js: createApp({ setup() { return { count:ref(0); }; }, template: ` Click! Clicks: {{ count }} `, }).mount("#app"); In this case, …  ( 6 min )

Marc Andreessen—the “MarcGPT” behind a16z and the first popular web browser—loves AI so much he calls it “our Philosopher’s Stone” and has plowed cash into OpenAI and Elon Musk’s xAI. He sees it as a universal problem-solver that’ll eventually do every job on Earth. But there’s one role he insists AI will never master: venture capitalist. On the latest a16z podcast, he argued that when machines handle everything else, VC will remain “quite literally timeless”—the last field where humans still call the shots.  ( 3 min )

In this context, the integration of artificial intelligence tools for real-time code suggestions—commonl…  ( 7 min )

Dissecting the HTTP Request — Line by Line Demystifying HTTP for Web Developers, Part 2 In Part 1 of this series, we traced the full journey of an HTTP request — from typing a URL in the browser, through DNS resolution and TCP handshakes, all the way to receiving the server’s response. But understanding the path a request travels is only half the story. To truly master HTTP, we now need to dissect the payload that actually moves across the wire: the HTTP request itself. Every interaction between a web client and a server begins with a carefully structured message — the request. It may look simple on the surface, but every line, header, and byte in that request carries meaning. If you’re building serious web applications, APIs, or even debugging flaky integrations, you can’t a…  ( 13 min )

Intro Ever doomscroll your way into developer rage? Yeah, me too. So yesterday I was minding my own business (aka avoiding Jira) when I stumbled upon a blog where some dude proudly declared: “Just finished 100 Days CSS Challenge!! 🥳🔥💯” Cool flex, bro. But when I clicked in, expecting juicy breakdowns, clever hacks, or at least some trauma bonding... all I got was: copy-paste StackOverflow energy, and I felt like I’d just been catfished by a portfolio piece. So naturally, I did what any mentally unwell developer would do — I challenged myself to do 100 Days CSS in 10 Days. Because why suffer slowly when you can suffer FAST? This series is for my fellow caffeine-fueled, chaos-coded siblings who want to actually learn something — not just vibe check another tutorial. If you’re insane lik…  ( 8 min )

In this post, I test how Mistral's Codestral, the model specifically trained to generate code, compares to the Mistral's Le Chat, the general AI chat. For my experiment, I use the Royal Game of Ur, an ancient Babylonian game that I already implemented using Le Chat. At least in my experiment, Codestral's performance is, frankly, disappointing. While it produces code that follows a certain architecture, the code quality is low. In fact, it even generates a statement of the form a = foo() where a has a different type from what foo() returns. Read on for more details. After the same prompt as with Le Chat, Codestral's response is: To implement the Royal Game of Ur in Python, we need to define several components: Game Board: Represent the board and the special squares.

Everyone’s in the cloud. Stacks have migrated. Infrastructure is containerized. CI/CD pipelines are green. But behind the wave of “cloudification”, one question lingers: Have we really changed the way we think? Because on the surface, everything looks modern. But underneath? ⏱️ Services running 24/7 💤 Containers sitting idle, waiting for traffic that never comes 💸 Bills growing, even when no one clicks “deploy” And in every retro, every finance meeting, the same old line: “The cloud is expensive.” But is it really the cloud that’s expensive? Or is it… The quiet luxury of feeding CPUs that are just bored? Let’s be honest. Cloud-native isn’t Docker. It’s not Kubernetes. It’s not Terraform, or some magic mix of YAML, containers, and CI/CD.

Introduction: So You Want Your LLM to Stop Guessing Everyone’s buzzing about Retrieval-Augmented Generation (RAG) like it’s the second coming of AI engineering. And honestly? It kinda is. Your large language model is excellent at confidently making things up—because it doesn’t actually know anything beyond whatever data it was last trained on (hello, 2023). That’s where RAG comes in: bolting on real, external knowledge so your LLM stops hallucinating and starts reasoning. But here’s the thing: knowledge isn’t just about facts. It’s about how things connect. And when relationships matter, you don’t want a flat file or a relational torture device. You want a graph. Enter the graph database.

In the first and second parts, we focused on creating two different patterns for handling data flow in React. EventTarget is the foundation of the browser’s event system. addEventListener, removeEventListener, and dispatchEvent. Many core Web APIs including DOM elements like , , , as well as document and window inherit from EventTarget. When we attach an event handler to a DOM element—like in the picture above—we’re actually subscribing to that element through one of its event channels. In this case: The button is the publisher (or emitter) The callback function passed to addEventListener is the subscriber (or listener) So when a user clicks the button, the button emits a 'click' event, and all registered listeners for that event type are notified and executed. So with…  ( 5 min )

I’m a product owner, guiding a team building a collaboration app for remote workers. Last quarter, we rushed a feature—real-time document editing—without thorough testing.

If you go back to the first talk ever given on webhooks, it opens on the command-line. Specifically the Unix shell, focusing on one of its defining features: pipes. The idea was that pipes brought a new level of compositionality to programs, and webhooks could bring a new level of compositionality to web apps. Perhaps you could say I was trying to bring the spirit of Unix to the web. With this last release of Wanix, I'm at it again. This time with the successor to Unix, a little known operating system called Plan 9 from Bell Labs. Plan 9 has been on my mind for quite a while. In fact, around the time of that first talk on webhooks, the team behind Unix and Plan 9 was being re-assembled to create the Go programming language.

O que é o Padrão Decorator? O Decorator é um padrão de projeto estrutural que permite adicionar comportamentos adicionais a um objeto de forma dinâmica. Ele permite que você encadeie funcionalidades (como validação, construção, logging e outras) em um fluxo sequencial, sem modificar a estrutura original da classe. Isso possibilita adicionar ou remover comportamentos com facilidade, mantendo o código mais flexível e desacoplado. Em resumo, o Decorator cria uma cadeia de responsabilidades onde cada classe pode adicionar sua funcionalidade à sequência, sem afetar as outras. Imagina que você precisa realizar várias validações (como validar o usuário, estoque e status), mas não quer que elas fiquem fortemente acopladas. O objetivo é poder adicionar, remover ou reorganizar facilmente as valida…  ( 4 min )

TS2327: Property '{0}' is optional in type '{1}' but required in type '{2}' TypeScript has quickly become a favorite tool for developers building scalable and maintainable JavaScript applications. At its core, TypeScript is a superset of JavaScript—it builds upon JavaScript by introducing static typing, as well as other modern programming concepts that make your code safer and easier to manage. Static typing means that developers can explicitly define the types of data (like string, number, or boolean) their variables and functions work with, catching potential errors during development instead of at runtime. If you're new to TypeScript, or want to sharpen your existing skills, consider following our blog or using advanced learning tools like gpteach.us to explore how modern AI tools ca…  ( 6 min )

TS2333: 'this' cannot be referenced in constructor arguments TypeScript is a statically-typed superset of JavaScript designed to add type safety and developer-friendly features to JavaScript code. A "superset" means that TypeScript builds on JavaScript by adding new functionalities, while still allowing you to write plain JavaScript. One of its most powerful features is the introduction of types (a system to define constraints on the structure of your data). This is immensely beneficial when working in large projects to detect errors at compile time, ensuring your codebase is reliable and maintainable. Types in TypeScript help us describe the shape of an object, function, or data. For instance, when you define a function or an object, you can explicitly specify what inputs it expects and…  ( 6 min )

TS2332: 'this' cannot be referenced in current location TypeScript is a popular open-source programming language developed by Microsoft. It’s often referred to as a superset of JavaScript because it builds on JavaScript by adding optional static types. These types allow developers to define the structure and behavior of variables, functions, and objects, making programs easier to debug and maintain. TypeScript compiles to plain JavaScript for execution, which means it seamlessly integrates with existing JavaScript projects. Simply put, types in TypeScript are what allow you to specify the kind of data a variable or function should handle. For instance, you can declare that a variable must always hold a number, a string, or a custom structure (like objects or classes). By catching errors …  ( 6 min )

TS2331: 'this' cannot be referenced in a module or namespace body TypeScript is a powerful language that builds upon JavaScript by adding optional static typing. By introducing "types" (representations of data such as strings, numbers, and objects, among others), TypeScript allows developers to write more predictable and maintainable code. It’s often referred to as a superset (a language that extends the features of another) of JavaScript, meaning all valid JavaScript code is also valid TypeScript code. A major advantage of TypeScript is its ability to catch errors during development, before the code is executed. However, while it enhances safety and boosts productivity, developers may sometimes encounter compiler errors that seem confusing at first. One such error is TS2331: 'this' ca…  ( 5 min )

TS2329: Index signature for type '{0}' is missing in type '{1}' TypeScript is a strongly typed superset of JavaScript. This means that it builds on top of JavaScript by adding an optional type system (a way to define and enforce the kinds of data being used in your code). TypeScript is a powerful language designed to catch errors early during development, making your JavaScript codebases more robust and maintainable. In TypeScript, "types" play a central role. A type defines the shape of data, specifying what kind of data will be stored, its expected structure, and the operations you can perform on it. For example, string, number, boolean, and object are common types used in TypeScript. Types ensure that your code only operates on the data it was designed to handle; if it doesn’t match t…  ( 6 min )

TS1433: Decorators may not be applied to 'this' parameters TypeScript is a strongly-typed programming language that builds on JavaScript by adding static types (data classifications, such as string or number). TypeScript helps developers write safer, more predictable code because it allows the compiler to catch potential bugs during the development process, before the code is executed. Essentially, TypeScript acts as a typed superset of JavaScript, meaning it includes all the features of JavaScript while adding new functionalities, mainly focused on type safety.

TS1434: Unexpected keyword or identifier TypeScript is a strongly typed programming language that builds on JavaScript, adding static types to the language. It is often referred to as a superset of JavaScript because it includes everything JavaScript offers while introducing additional features such as types, interfaces, and enums, which help developers catch errors at compile time rather than runtime. In TypeScript, "types" are a mechanism to define the shape, structure, or behavior of data in your programs, ensuring that your code operates exactly as intended. If you're interested in understanding and mastering TypeScript—or using AI tools to streamline your learning—consider subscribing to our blog. Additionally, tools like GPTeach can be a great way to learn coding concepts faster a…  ( 5 min )

Introduction to Tokenization In recent years, the world of finance has seen significant advancements, especially with the introduction of blockchain technology. One of the most exciting developments in this space is the concept of tokenization, particularly the tokenization of U.S. equities (stocks). But what exactly does tokenization mean, and why is it so important for U.S. equities? What is Tokenization? Tokenization refers to the process of converting ownership of an asset, such as stocks, real estate, or artwork, into a digital token on a blockchain. This token represents ownership or a portion of ownership of the underlying asset. In the case of U.S. equities, tokenization means turning traditional company shares into digital tokens that are recorded on a blockchain ledger. Blockcha…  ( 8 min )

How I built VidSabio.com by combining multiple LLMs into a robust processing pipeline I recently launched VidSabio, a platform that transforms ordinary videos into structured, interactive learning experiences — automatically. 🎥➡️📚 But this didn’t come together overnight. At first, I thought a single LLM could handle everything: analyze the video, transcribe it, generate quizzes, build a course. Easy, right? Wrong. It turned out the real breakthrough came when I stopped looking for one model to do it all — and instead built a pipeline of specialized steps, each powered by the best tool for that specific task. Here’s the high-level breakdown of how it works: User uploads a video Video is processed through a multi-step pipeline: Frame extraction (FFmpeg) Audio transcription (Google Speech-to-Text) Visual analysis (Gemini / GPT-4 Vision) Content summarization + topic generation (Gemini Pro) Course structure generation (GPT-4) Interactivity injection (quizzes, accordions, etc.) Final course can be edited and exported as SCORM or HTML This is all built using Vue 3, Firebase, and various LLMs (OpenAI + Gemini) stitched together through Cloud Functions. By distributing the heavy lifting across multiple LLMs and APIs, I was able to: Improve accuracy Scale more efficiently Debug and retry isolated steps Customize outputs based on step-level feedback Frontend: Vue 3 + Tailwind Backend: Firebase Functions + Firestore + Storage AI: GPT-4.1, Gemini Pro, Whisper, Google Speech-to-Text Analytics: PostHog Export: SCORM, HTML Here's a stylized diagram of the flow: (Insert your HappyAlien-styled image here) This was built with plenty of detours, dead ends, and "aha" moments. If you're building with LLMs, I encourage you to explore multi-model orchestration — it might be the key to your next breakthrough. Check it out: https://vidsabio.com Feel free to reach out if you’re curious or building something similar!  ( 3 min )

Hey DEV community! I just launched a side project I’ve been tinkering with: GitVisualize It lets you paste in any public GitHub repo URL, and it’ll generate a visual representation of that project using OpenAI’s gpt-image-1 model — all based on the repo’s README content. Takes a GitHub repo URL Pulls the README Feeds it to an AI image model Displays the generated image alongside project metadata Adds it to a public gallery You can even choose the image style you want: Conceptual & Techy Infographic Abstract & Minimalist Direct & Clear It’s built with Vue 3 + Tailwind, uses Supabase for storage and data, and everything runs through a lightweight backend on Render. I love browsing GitHub, and I wondered: “What would this project look like if it were a picture?” So I built GitVisualize as a fun experiment in combining AI, dev culture, and a bit of creativity. Some of the results are surprisingly expressive.

A piece of feedback that reshaped how I think about conviction, consensus, and presence when you're the most senior person in the room. Originally published at mustafatorun.me A few years ago, I wrote a design document outlining a few different options. It was for a group more experienced than me—not in the domain, but in the industry. I knew the problem well. I had done the work. But still, I softened my position. I showed the tradeoffs, invited discussion, and held back from saying with confidence, “This is the direction I believe we should take.” In a pre-review, someone I trusted — someone more experienced than me — called it out. The document lacked conviction. It read like I was asking the group to decide for me. They reminded me that I was the expert in this domain — not them. What …  ( 4 min )

You’ve been forced to maintain a poorly written legacy app. Spaghetti code, no tests, and every new feature breaks two existing ones. Team morale is at rock bottom. New features take forever to ship. Regression bugs are constant. You gather your arguments and head to management. You: We need time to refactor. Management: What are you talking about? You: Let us refactor. We’ll ship faster, with fewer bugs, and engineers won’t want to quit. I can do it. Management: ...Okay. Now comes the hard part. Are you going to deliver on your promises? Or end up behind schedule and still stuck with a spaghetti codebase?

If you’ve started learning JavaScript, you’ve probably worked with arrays — those magical lists that hold multiple values. But knowing how to use arrays effectively means understanding the array functions that JavaScript gives us. Let’s break down the most powerful and commonly used array functions that every developer should know. An array is a special variable in JavaScript that can hold more than one value at a time: const fruits = ['apple', 'banana', 'cherry']; .push() – Add to the End fruits.push('mango'); console.log(fruits); // ['apple', 'banana', 'cherry', 'mango'] .pop() – Remove from the End fruits.pop(); console.log(fruits); // ['apple', 'banana', 'cherry'] .shift() – Remove from the Start fruits.shift(); console.log(fruits); // ['banana', 'cherry'] .unshift()…  ( 4 min )

When working with APIs, we often encounter data in formats that do not match our application's preferred coding style. For instance, if you're using TypeScript and Vue.js, you might receive data in snake_case from an API but prefer to work with camelCase throughout your application. The good news is that you can easily transform this data without losing type safety. Let's delve into how you can achieve that with the help of interfaces and utility types in TypeScript. Understanding the Problem When you define an interface such as MergedReviewDetails, you structure your data according to your application's needs. An example of this could be: export interface MergedReviewDetails { parentReview: Mmcid; childReviews: Mmcid[]; } However, the API might return data with properties in snake_ca…  ( 4 min )

In the world of corporate security, not all breaches involve sophisticated hacking tools—some simply walk through the front door. Tailgating, a subtle yet dangerous form of intrusion, happens when an unauthorized person gains access to a restricted area by following closely behind someone who is authorized. It's a tactic that relies less on technology and more on exploiting human behavior. Attackers often masquerade as employees, contractors, or delivery workers. They may carry packages, wear uniforms, or claim to have forgotten their access badge—all to lower suspicion. Once inside, these individuals can do far more than just roam the premises. They might access critical systems, plant malicious software, or steal sensitive equipment. Pretending to be a colleague and asking someone to hol…  ( 4 min )

It was a regular evening debug session. My code was working, but something about it just felt off. I was looping over a list—like always. for i in range(len(my_list)): value = my_list[i] # Do something with value and i Nothing wrong, right? Except... I was starting to hate reading my own code. range(len(...)). Too much manual indexing. 👀 The Realization for i, value in enumerate(my_list): # Do something with i and value Wait... what? No range(len(...))? No messy indexing? ✅ Cleaner 🧠 Why it works: enumerate() is a built-in Python function that returns both the index and the value of items in an iterable—in one shot. It’s like your loop suddenly gained superpowers. 💡 Bonus Tip: for i, val in enumerate(my_list, start=1): print(f"Item {i}: {val}") Perfect for user-facing counters. No more +1 hacks. 🚫 Never Again... No more range(len(...)) unless I really need it. Now, it’s all enumerate(), all day. ✨ Moral of the Story: If you're reaching for range(len(...)), stop and ask yourself— What would enumerate() do? 😎  ( 3 min )

When working with Lumerical FDTD simulations, access to specific fields from the results of a far-field projection monitor might sometimes be challenging, especially when it comes to field names with spaces. In your case, you're able to access standard fields like E2 and Es easily: farfield = getresult("monitor", "farfield"); E2 = farfield.E2; Es = farfield.Es; However, when it comes to the field "Ep vs angle", an error arises. This can happen due to the space in the field name, making direct access using dot notation invalid. Understanding the Structure of the Farfield Object The farfield object typically contains several fields, including E2, Es, and multiple arrays or matrices concerning angles and wavelengths. The fields you can access directly using dot notation are designed to be id…  ( 4 min )

RDMA(Remote Direct Memory Access)는 네트워크를 통해 서버 간에 CPU 개입 없이 메모리를 직접 읽고 쓰는 기술이다. 주로 고성능 컴퓨팅(HPC), 대규모 데이터 처리, AI/ML 분산 학습 환경 등에서 낮은 지연 시간과 높은 대역폭을 제공하기 때문에 많이 사용한다. 1. RDMA의 기본 개념 일반적인 네트워크 통신 방식에서는 데이터를 전송하려면 CPU가 메모리에서 데이터를 읽고, 네트워크 인터페이스 카드(NIC)로 복사한다. 이 복사한 데이터를 네트워크를 통해 데이터를 보내고, 수신 측에서도 CPU가 데이터를 NIC에서 메모리로 복사한다. 이 과정에서 CPU, 커널, 복사 작업 등이 개입되어 지연(latency)과 CPU 오버헤드가 큰 현상이 발생한다. 반면, RDMA는, CPU나 운영체제(OS) 커널의 개입 없이, 원격 시스템의 메모리에 직접 읽기(read) 또는 쓰기(write) 작업을 수행한다. 다시 말해, 데이터가 직접 메모리에서 메모리로 이동한다. 2. RDMA가 동작하는 방식 (1) 메모리 등록 (Memory Registration) 송신자와 수신자 모두 RDMA NIC(HCA: Host Channel Adapter)를 사용함. RDMA를 사용하기 위해서는 사용할 메모리 영역을 등록(pinning)해야 함. 이 과정에서 해당 메모리는 물리 메모리에 고정되고 커널이 RDMA NIC에 메모리 주소를 알려줌. (2) Queue Pair 생성 RDMA 통신은 QP(Queue Pair)라는 구조를 통해 이루어짐. QP는 Send Queue와 Receive Queue로 구성…  ( 4 min )

The Scraper: The Collector of Car Parts Each day, the Scraper ventured out, gathering essential tools—brake pads, spark plugs, and oil filters—meticulously putting them in his storage room. This storage room, filled with parts, was like a database, organizing all the precious data he gathered from various sources. For instance, one day, the Scraper found a batch of brake pads. He cataloged the details, from brand to condition, and stored it safely. This was like collecting the latest prices from websites, storing them in a file for future use. The Backend Guy: The Toolbox Handler Whenever the mechanic—the Frontend—needed a specific tool, they would call out, “I need a 10mm wrench!” The Backend Guy, standing by the toolbox, would find the correct tool and hand it over with precision. He didn't fix the car himself, but he made sure the mechanic had exactly what was needed at the right time. Just like that, the Backend Guy managed the storage of all the data and ensured it was always ready when the Frontend needed it. When the mechanic asked for the current price of the Euro in Toman, the Backend would retrieve that data and send it in a neat package—a JSON response—ready to be used. The Frontend Mechanic: The User Interface When the mechanic needed a part, they'd shout, "I need a 10mm wrench!" The Backend Guy would respond, handing over the tool, and the Frontend Mechanic would get to work. The mechanic didn’t care how the part got there, as long as it was the right one. In the same way, the Frontend Mechanic used the data provided by the Backend to create an amazing display for the car's dashboard. They made sure the car (or website) looked stunning, with neatly organized parts (like the prices) and a smooth-running engine (user interface). Whether it was showing prices in a nice table or providing a simple, user-friendly experience, the Frontend Mechanic made sure everything was visually appealing and functional.  ( 4 min )

Infrastructure as Code (IaC) has come a long way since its beginnings. What started as spinning up cloud resources has now grown into a full-blown ecosystem with a very engaged community. IaC on its own can add a lot of complexity to your processes and cause more issues, but combined with governance, compliance, security, deployment strategies, self-service, it easily becomes the fuel your delivery engine needs. This year, IaCConf debuts as a virtual event by bringing together this community, and it’s shaping up to be one of the most relevant and practical events in the space. Unlike broader DevOps/SRE or cloud-native events, IACConf is focused on the challenges and innovations around defining infrastructure as code. That means the content goes deeper, the conversations are more relevant, and the takeaways are directly applicable to your processes. There will be sessions on: Getting started with IaC Managing IaC at scale across teams and environments (using OpenTofu, Terraform, Ansible, Crossplane, and others) Platform Engineering and IaC How IaC impacts your maturity AI in IaC And that’s just scratching the surface. Check out the full agenda here. One of the things I appreciate most about this conference is that it’s not about product pitches or high-level fluff. Practitioners share what worked, what broke, and how they improved. Whether you are just starting out, are in the trenches, or shaping platform strategy, there’s something for you here. On another note, I’m also excited to contribute to this year’s lineup with a session on Getting Started with IaC, together with my colleague Emin Alemdar. But honestly, I’m just as excited to learn and to connect with others working through the same challenges. The event will be on Thu, May 15, 2025 @ 11:00am EDT, so don’t forget to register here.

By a beginner, for beginners. When I first started learning Go (Golang), everything felt a little strange. Coming from the Python and JavaScript background😅😅., I expected to deal with new syntax, but I didn’t expect to get stuck on the very first line of every Go file: package main I remember asking myself: "Why do we declare the package name before the start of any code?" 📦 What Is a Package in Go? In Go, as well as other languages like Python, a package is a way to organize and reuse code. Every .go file must start by declaring which package it belongs to. There are two kinds of packages you’ll encounter early on: main: This package is special. It tells the Go compiler that this file is part of an executable program. Library packages: These are packages meant to be imported into othe…  ( 4 min )

Suppose you have a busy website where elements are constantly changing, buttons appear, text updates, new content sneaks in. You need a detective to watch all of this.

In Rust, understanding how std::mem::transmute functions between different types is crucial for ensuring memory safety and type integrity. This brings us to an interesting question: Is it safe to transmute between two custom struct types, OuterA and OuterB, which only differ by their inner types — InnerA and InnerB? Let's explore what the repr(transparent) conveys and clarify the implications of transmuting types in Rust. Understanding repr(transparent) The #[repr(transparent)] attribute in Rust is used to indicate that a struct represents a single variant of a type that can be safely treated as equivalent to its single field. This is particularly useful for effectively working with opaque types or for implementing newtype patterns. In the provided example, we have the following structur…  ( 4 min )

Introduction When developing Angular applications, particularly with Angular Material, you might encounter issues regarding the mat-list and mat-divider components. Many developers wonder whether to use ngFor inside the mat-list or the mat-list-item and how to correctly place the mat-divider. Let’s delve into this topic to clarify which method is best. Why This Issue Arises The confusion around where to implement ngFor and the positioning of mat-divider often stems from how Angular handles component rendering. Using ngFor within the mat-list means that each item is rendered as part of the list itself; thus, the dividers are less likely to show correctly if their placement isn’t considered carefully. Conversely, applying ngFor to mat-list-item makes each list item independent and potentiall…  ( 4 min )

A proxy firewall, often referred to as an application-layer or gateway firewall, acts as an intermediary between a user’s system and external servers. Instead of allowing direct communication, it processes and forwards requests on behalf of users. This not only hides internal network details from outsiders but also allows the firewall to thoroughly inspect data before it reaches its destination. Unlike traditional firewalls that operate primarily at the network or transport layer, proxy firewalls operate at the application layer. They intercept requests, evaluate the content, and relay approved traffic. This additional layer of inspection allows for more granular control, helping detect threats embedded in seemingly legitimate requests—such as malware hidden in web traffic or email attachm…  ( 4 min )

Hello, I have an ambitious technical idea that I hope to share with the community of developers and cybersecurity specialists: Given the widespread prevalence of pornographic content online, and the difficulty of controlling it through traditional blocking or weak censorship tools, I've come up with a new system: 🔐 An "ethical operating system" (for smart devices – such as Android, iOS, and Windows) built from the ground up on the principle of: "Completely blocking any type of pornographic content, whether visual or textual, whether on websites, apps, search engines, or social networks." 💡 Key features of the idea: Its protection cannot be hacked or changed (such as the inability to install an alternative system). It can be installed on children's devices, school devices, or even the devices of adults who want to protect themselves. It doesn't rely solely on blocking a specific site, but rather on real-time content analysis. A clean app store and a clean built-in search engine. 🧱 Technically: Or as a distribution for children, schools, or conservative environments. Or even as a layer of security added to existing systems (e.g., Android). 🎯 The goal is not to impose censorship, but rather to provide a safe, ethical, and educational alternative. 🤝 I'm looking for: Interested programmers. Note that I'm only 16 years old. The goal is to find someone who will embrace this idea. Suggestions for improving the idea. Any technical or community support is possible.

In a world of growing email threats, a brand impersonation is one of the most damaging and widespread forms of phishing. As we know that organizations need more than just secure email delivery — they need visible proof of authenticity. That is why BIMI (Brand Indicators for Message Identification) comes into play. Actually BIMI allows brands to display their logo directly in recipients’ inboxes, that offering visual trust and higher engagement. However, for BIMI to function, it must depend on strong email authentication protocols already in place. BIMI is a standard that lets organizations to publish their brand logo in a specific format (SVG) through DNS. When supported by the mailbox provider, actually the logo appears next to the authenticated emails in the recipient’s inbox. This not …  ( 5 min )

Overview In today's digital landscape, creating compelling and polished content is essential for capturing and retaining audience attention. The publication should not be overly dense or difficult to read. 2500 words. On the other hand, the size should not be too small, where it can be consumed in just one minute. 800 words as the smallest size for a publication. An important point to note is the absence of any formatting symbols in the publication, such as or   . There is a recommendation for citations to be formatted as in-line links, with any recommended reading listed separately. If you use tables in your publications, please make sure that columns with less content are placed towards the end of the table, and vice versa. Additionally, I suggest placing more important columns at th…  ( 5 min )

When working with web custom elements in TypeScript, many developers find themselves needing to implement lifecycle callbacks such as connectedCallback(), adoptedCallback(), and attributeChangedCallback(). These methods are essential for managing your custom element’s lifecycle, but the implementation can often be confusing, especially regarding TypeScript type definitions. Understanding Custom Element Lifecycle Callbacks Custom elements are part of the Web Components standard, allowing developers to create reusable components encapsulated in their own HTML tags. Each custom element undergoes various lifecycle events as it is created, added to the DOM, updated, or removed. These lifecycle methods play a critical role: connectedCallback(): Invoked when the custom element is first connected …  ( 4 min )

Over the years, I’ve interviewed around 100 software developers at Google and roughly the same number across my own companies. One thing has become very clear: Resumes don’t work. They’re too noisy. You get flooded with titles, buzzwords, and irrelevant project summaries. So I distilled everything down to one single task. One prompt I can give to anyone — junior or architect — and instantly get a signal. The task? Write a library that calculates the sum of a vector of values. That’s it. No extra requirements. The beauty is that it looks trivial — but the depth reveals itself as the candidate explores edge cases, generalization, scalability, performance, and design. Most junior candidates start like this: int Sum(int* data, size_t num_elements) { int result = 0; for (size_t i = 0; i…  ( 5 min )

Objective-C has long been a mainstay in the development of applications for iOS and macOS. Despite the rise of Swift, Objective-C remains a relevant and powerful language, particularly for maintaining legacy code and integrating with newer Swift code bases. As we move into 2025, understanding core patterns like delegation continues to be vital for developers working with Objective-C. Delegation is a design pattern used in Objective-C to pass messages between objects and to provide a mechanism for customization of behavior. It allows one object to delegate tasks to another, enabling a clear separation of responsibilities and enhancing the modularity of applications. Typically, a delegate object implements methods from a protocol to respond to certain events or actions occurring in the deleg…  ( 4 min )

In one of our production data platforms, we used Lambda functions to trigger AWS Glue jobs every time a file landed in an S3 folder. That setup worked fine when there were only two or three data sources. But as the system expanded to support more than 10 folders, it required deploying and maintaining an equal number of nearly identical Lambda functions, each wired to specific prefixes and jobs. The architecture became increasingly brittle and harder to manage. This post outlines how that structure was replaced using EventBridge, with prefix-based filtering and direct Glue job targets. No Lambda. No maintenance overhead. Using S3 events to trigger Lambda comes with several limitations: A single Lambda function can’t be mapped to multiple S3 prefixes Each one requires separate deploymen…  ( 5 min )

To Understand Encapsulation please do check out last post Encapsulation is like a medicine capsule: the outer shell hides the complex ingredient inside, delivering only the intended effect to your body. You don't need to know the chemical makeup to benefit from it. Encapsulation is achieved through the use of access modifiers. Python primarily uses two types of access modifier. Private: Accessible from anywhere. Public: Accessible only within the class. Similarly, in programming, encapsulation wraps data and methods in a class, exposing a simple, controlled interface while keeping the internal details private and secure. Let say I want to make "model" attribute private so that nobody can manipulate the model name. So make it private just add '__model' So, question arise if we can't access attribute but we can access function which include the private attribute. Think of like if we have attribute which you don't want get manipulated then make it private.  ( 3 min )

Introduction If you're developing a MAUI application and are facing issues with the CarouselView control not displaying images from an ObservableCollection, you are not alone. This article will address why images may not show up in your CarouselView, even when the same image sources work perfectly with a standard Image control. Understanding CarouselView in MAUI The CarouselView in .NET MAUI is designed to display a collection of items in a swipeable format. Each item can be customized using a DataTemplate, which lets you define how each item appears. Typically, developers use ObservableCollection to bind dynamic data to CarouselView because it notifies the view of changes. However, while you may see indicators appear correctly, images may not load as expected. Common Issues with CarouselV…  ( 4 min )

Objective-C, a primary programming language used for macOS and iOS development, has always been appreciated for its unique blend of C's efficiency and Smalltalk's dynamism. A critical feature that sets it apart from other languages is its support for **dynamic typing**. This allows for a flexible development process that enhances code modularity and adaptability. But what truly is the purpose of dynamic typing in Objective-C? ## What is Dynamic Typing? Dynamic typing refers to the ability of a programming language to determine the type of an object at runtime, rather than during compile-time. This contrasts with static typing, where the type of an object is known and enforced during compilation. In Objective-C, this means you do not have to specify the class type of an object, providing …  ( 4 min )

If you're still not using Tailwind CSS JIT (Just-in-Time) mode in your development workflow, you're seriously missing out on one of the biggest productivity boosts Tailwind has ever introduced. The JIT compiler doesn't just make your builds faster—it fundamentally changes the way you write utility-first CSS. Once you try it, there’s no going back. Let’s break down why it's a game-changer for modern frontend developers, and how to make the most of it. JIT mode was introduced as a way to: Compile only the CSS classes you actually use Instantly reflect changes as you code Drastically reduce build times and output file size Enable dynamic class generation Instead of scanning your entire project ahead of time, it compiles your CSS on-demand as you save files. That means faster feedbac…  ( 4 min )

Selecting messages with a specified sum of verbosity can be challenging in SQL, especially when the goal is to find all messages where the sum of a specific column stays below a certain threshold. In this case, we want to find messages from a table with a specified verbosity value such that the summed values of verbosity for a given set of rows remain under a specified limit, N. Understanding the Problem In our example, we have a simple table named messages, which contains two columns: id and verbosity. Given the entries: | id | verbosity | |----|-----------| | 1 | 20 | | 2 | 20 | | 3 | 20 | | 4 | 30 | | 5 | 100 | When we wish to choose rows whose sum of verbosity is less than a certain value, say N = 70, we expect to select the rows with ids 1, 2, an…  ( 4 min )

Flutter makes building beautiful UIs fast and fun — but what happens when your app starts growing? When screens need to react to shared data? That’s when state management becomes essential. In this blog, we'll demystify state management in Flutter and help you decide between Bloc, Riverpod, and Provider — three of the most popular approaches in the Flutter ecosystem. State refers to the data your UI depends on. For example: A counter’s value Whether the user is logged in The list of items in a shopping cart State management is how we keep the UI in sync with the data — especially when multiple widgets care about the same data or when data changes over time. There are two broad types: Local state (e.g., setState inside a single widget) Global/shared state (e.g., auth status, theme, user pre…  ( 5 min )

Introduction If you're using Java Development Kit (JDK) 17 and noticing that your call to fieldClass.getDeclaredFields() returns an empty array, you're not alone. Many developers have encountered this issue when attempting to retrieve field information from classes in the Java Reflection API. The Java Reflection API is essential for inspecting classes at runtime, allowing developers to gather information about fields, methods, and constructors programmatically. However, certain security restrictions in JDK 17 can lead to unexpected behavior, including the inability to reflectively access declared fields in classes like Field.class from the java.lang.reflect package. Understanding the Root Cause In JDK 17, Java introduced a more robust module system that enforces strong encapsulation by def…  ( 5 min )

Fine-tuning in Artificial Intelligence (AI) refers to the process of taking a pre-trained model and adapting it to a specific task or dataset. Pre-trained models, especially large ones like GPT (from OpenAI) or BERT (from Google), are initially trained on massive datasets using general-purpose data. These models learn a broad understanding of language, patterns, or image features. However, for specialized tasks—like medical diagnosis, legal document analysis, or customer sentiment detection—fine-tuning helps the model learn domain-specific nuances. The process involves continuing the training of the model with a smaller, task-specific dataset while adjusting the model’s weights slightly. This method allows the model to retain its general knowledge while becoming more effective in the target domain. Fine-tuning is far more efficient than training a model from scratch, saving both computational resources and time. There are different levels of fine-tuning. Some approaches adjust only the final layers of the neural network (known as feature extraction), while others allow all layers to be updated (full fine-tuning). Techniques like parameter-efficient fine-tuning (PEFT), such as LoRA (Low-Rank Adaptation), are gaining popularity, especially for large language models, because they minimize the number of parameters updated. Fine-tuning is used in a variety of real-world applications, including chatbots, image generation, fraud detection, and more. It’s especially powerful in scenarios where labeled data is limited but high-quality outputs are essential. With the growth of open-source and pre-trained foundation models, fine-tuning has become a key skill for AI practitioners. To master techniques like fine-tuning, transfer learning, and prompt engineering, enrolling in a Generative AI certification course is highly recommended.  ( 3 min )

Abstract We introduce a novel numerical method, ExpRoot+Log, for function approximation based on a hybrid linear basis consisting of exponential-square-root, polynomial, and logarithmic components. This method achieves high accuracy across smooth, discontinuous, and rapidly decaying functions while remaining simple, interpretable, and computationally efficient. We show that ExpRoot+Log outperforms classical approaches such as polynomials, splines, Fourier series, and even neural networks in key scenarios, offering a new universal baseline for practical approximation. Introduction Function approximation is fundamental to numerical analysis, physics, machine learning, and signal processing. Classical bases—polynomials, splines, and trigonometric functions—have known limitations, especially near discontinuities or exponential decays. While neural networks provide expressive power, they are complex, opaque, and computationally expensive. We propose a new hybrid basis: This composition handles: All coefficients are learned linearly (e.g., via least-squares), ensuring ultra-fast performance and excellent stability. Numerical Evaluation We tested ExpRoot+Log against standard methods (polynomials, splines, Fourier) across six function types: Sine Exponential decay Step function Gaussian spike Absolute value Composite (piecewise mix) ExpRoot+Log consistently achieved 1–4 orders of magnitude lower error than polynomials or Fourier bases.

Introduction If you've encountered the error message while building your Flutter APK, such as ERROR: R8: java.lang.IllegalArgumentException: Provided Metadata instance has version 2.1.0, while maximum supported version is 2.0.0, you're not alone. Many Flutter developers face similar issues, particularly related to the R8 code shrinker. This article will guide you through understanding why this error occurs and how to fix it effectively. Why Does This Error Occur? The error appears when the Kotlin metadata version specified in your dependencies isn't compatible with the version used by the R8 shrinker in your build process. In your case, it indicates that the kotlinx-metadata-jvm library version you're using likely exceeds the maximum version supported by R8—2.0.0. If you've installed an up…  ( 4 min )

Problem description & analysis: The database table tbl has a string field DESCRIPTION. Task: Now we need to retrieve the word ‘EN’ and the subsequent string of numbers from the DESCRIPTION field. The string of numbers may consist entirely of digits, such as ‘10204’, or it may contain special characters, such as ‘10277/10’. Caution: Do not retrieve punctuation marks; If the string does not contain ‘EN’, return null.

Access Control Models: ACL, RBAC, ABAC In system design, access control is a critical mechanism to ensure data security and correct authorization of functionalities. Depending on the complexity of the system, the variety of user roles, and the flexibility needed in resource management, there are three common access control models: ACL (Access Control List), RBAC (Role-Based Access Control), and ABAC (Attribute-Based Access Control). Below is a brief comparison of these three models, outlining their design logic, characteristics, and application scenarios to help clarify the selection and implementation considerations. Direct authorization, fine-grained, but difficult to manage Design Logic: User → Resource + Operation If a user has read and update permissions for the development departme…  ( 4 min )

Last March 22, hundreds of makers, students, educators, and tech advocates gathered at STI College Cubao for Arduino Day Philippines 2025, joining the global celebration of 20 years of Arduino and open source innovation. With the theme “Celebrating 20 Years of Arduino and Open Source Innovation,” this year’s event became more than just a commemoration—it was a powerful reflection of how far the local tech community has come and where it’s headed next. The event opened with warm welcomes from Marvin James Erosa and Jeferson De Leon, immediately setting a collaborative tone for the day.

But from there, it was all systems go—talks, workshops, demos, and inspiring stories from all corne…  ( 5 min )

Somewhere between thinking and speaking, there’s a strange place where meaning starts to solidify. It’s not quite a word yet. More like a haze of associations. A mental sketch your brain tries to translate into something shareable. Sometimes it works. Most of the time it doesn’t, at least for me. I tend to mumble a lot. That private language in your head, the one you use to talk to yourself, isn’t English or Portuguese or Python. It’s not even a language, really. It’s raw and messy. A kind of silent shorthand sculpted by experience. Try catching it. Try explaining it. It slips through like fog in your fingers. Science is already poking around in there. Researchers are feeding brain signals into neural networks and getting fuzzy images back. They’re trying to reverse-engineer what we see, d…  ( 7 min )

Introduction When developing an application that requires seamless data exchange between C# and PHP, maintaining character integrity is crucial. If you've encountered issues where characters like 'é' appear as 'é' after data transfer, you're likely facing a character encoding problem. This article will guide you through understanding character encoding and how to resolve these issues effectively. Understanding Character Encoding Issues Character encoding is essential for correctly displaying and processing text data. In your case, both the C# application and the PHP server are set to use UTF-8, but inconsistencies can arise during data transfers. This usually occurs when data is transformed in a way that misinterprets the byte sequences of special characters, leading to the corruption of …  ( 4 min )

We talk about writing better test cases, improving coverage, and spotting edge cases early. But rarely do we talk about how those same instincts apply to hiring. And within 2 hours? Most Job Posts Are Noise Vague requirements Tools thrown in without context Unrealistic experience levels (10 years of Cypress? Sure.) Zero clue what kind of thinking the role actually needs I didn't want that. So I stripped it down and wrote it like I write tests: clear, intentional, and designed to reveal behavior. I ended the post with a line that acted like a trapdoor: “Want in? Send your resume and a short note on how you found your worst bug to hi@proudcloud.io.” That was the test. If you missed it, you failed silently. The Best Testers Didn’t Just Apply. They Investigated. But a smaller group took the time, wrote thoughtful bug stories, and sent real applications to the email provided. And those were the ones I called in for interviews. Some of the best candidates I’ve ever spoken to came from that post. Sound familiar? This Isn’t Just About Hiring The way you write a bug report. The way you name a test. The way you respond when something feels off, even if the build says "green." QA is never just about tools. It's about how you think.

Originally posted at https://qckfx.com/blog/why-engineering-teams-should-build-their-own-ai-coding-agents Imagine walking into an engineering department three years from now. The highest-performing teams will be defined by the proprietary AI systems they've built, customized for their specific codebases, architectural patterns, and business domains. These teams will wield AI as a strategic differentiator, not merely consume it. This is where our industry is clearly headed. As AI increasingly becomes the primary author of code across industries, the strategic advantage will shift from who can write the best code to who can best direct, customize, and optimize AI systems to write that code. The best engineering teams won't achieve these results by simply adopting off-the-shelf AI coding tool…  ( 7 min )

I've worked in several agile teams as both a developer and lead developer. One particular project sticks in my mind — a team of ten people, dozens of microservices, and a lot of GitLab repositories to manage. During each sprint, we were juggling features across multiple repos. At the same time, we were responsible for reviewing each other’s code. Our typical flow was: Open a merge request (MR) on GitLab Move the related Jira ticket Share the MR link in a Teams channel Move on to the next story When the workload was light, it was manageable. But in busy sprints, reviews piled up quickly. Large MRs got ignored, or rushed through. And tracking what was waiting, what was blocked, or what still needed input? A mess. We experimented with several ideas: Using GitLab labels like needs-review or blocked Adding Jira tags Rotating reviewer ownership by repo each sprint They helped — but they didn’t solve the root problem: lack of visibility and timing. Code reviews were often asynchronous and scattered. We were switching contexts constantly, jumping between repos, and forgetting which contributions needed our attention. We didn’t need more tools — we needed a better way to surface and track reviews. Something that would: Give us a unified view of MRs Let us know what’s ready to merge, what’s waiting, and what’s blocked Respect our flow, instead of interrupting it That’s when I started working on a side project, aiming to solve this specific pain point. That side project became Bellugo — a contribution tracker designed to help teams stay on top of reviews across repositories without the chaos. It’s still a work in progress, but if this resonates with your team, I’d love for you to check out the landing page and maybe join the private beta waitlist.  ( 4 min )

So, you're self-hosting awesome apps like Jellyfin, Home Assistant, or your personal blog with Docker. You want that sweet, sweet HTTPS padlock for secure connections, and Let's Encrypt is the obvious choice for free SSL certs. Awesome! You set up your reverse proxy (maybe Traefik, because it's slick!), point it to your app, and tell it to get a certificate... only to hit a wall. Why? Meet the home networker's nemesis: ISPs blocking incoming port 80. The Standard Way (and the Wall) Let's Encrypt's default validation method, HTTP-01, is simple: their servers try to access a special file on your server over standard HTTP (port 80) to prove you control the domain. Let's Encrypt -> Your Public IP:80 -> Does challenge file exist? -> OK! Cert Issued! But if your ISP blocks incoming connections …  ( 5 min )

Learning Redux is a real pain in the @#$#$^&. Good thing the team I was on at the time I learned it highly valued taking the time to learn, because it took me a good 30 out of 40 hours of a work week to figure out what the eff was going on. Once I finally did learn it however, I realized that the majority of what slowed me down in the learning process was that I couldn’t find a great explanation of exactly what Redux was doing. All I could find were tutorials on how to use it, and not really very much info on how it worked. I’m going to try to solve that issue with this post. I’m also going to assume that you know how to use React, and that you know what Redux is and why you want to learn it. I’m also only covering the very basics of Redux and what you need to know to be able to hopefull…  ( 5 min )

The Testing Time Crisis When our team started building a new fintech application last year, we hit an unexpected bottleneck: testing time. With multiple user roles, complex verification flows, and strict security requirements, our QA cycles grew from days to weeks. This wasn't just frustrating—it was directly impacting our release velocity and team morale. After several painful sprints, we implemented five changes to our testing approach that dramatically reduced our testing time without compromising quality. I'm sharing these because they've been game-changers for us, and they might help your team too. One of our biggest time sinks was manually creating test users with different permission levels. We solved this with an automated provisioning system. // Example of our user provisioning …  ( 5 min )

Introduction As developers, we all face the hidden challenge that rarely gets discussed in coding tutorials: generating and managing test user data at scale. This becomes particularly problematic when building applications requiring email verification, multi-user testing, or complex authentication flows.

🎯 Learning Goals What are the characteristics of Singly Linked Lists? What are its time complexities? ListNode? Has a value and a next pointer next is a reference to another ListNode Order in memory may not be contiguous (unlike arrays which are) Simple while loop with a current pointer can be used: cur = ListNode1 while cur: cur = cur.next ⌚ Time complexity is O(n) , where n is the number of nodes in the linked list Now if the Linked List is circular (i.e. last node points back to first) traversing like this would cause an infinite loop. It would be helpful if we’re keeping track of the head and the tail of the linked list using pointers Advantage over array is that inserting is always O(1) even if we insert in middle. Let’s say we wanna add at the end or tail : tail.next = NewListNode tail = NewListNode # or this line 'tail = tail.next', both are correct ⌚ Time complexity is O(1) Removing any node is constant time ASSUMING we have a pointer to the previous node. Let’s say we wanna remove the second node: head.next = head.next.next # Just set the next pointer of head to the one after the deleted node Can be assumed that garbage collection will take place for the deleted node ⌚ Time complexity is O(1) For both of these operations, the caveat is if we don’t have a reference to the node at the desired position (head or tail), the time will still be O(n) Operation Big-O Reading/ Access O(n) Traversal/ Search O(n) Insertion O(1)* Deletion O(1)* *Assumes you have a reference to the node at the position (if not it is O(n) ) 206.
